You're developing an open-world game. How can you let player decisions shape the narrative organically?

It's also crucial to not go overboard with branching decisions. It requires significant time and resources which can compromise the quality of each narrative path. Players may also miss out on significant portions of the game's content if they choose one path over the other which may include missing out on unique quests, character interactions, or storylines that are exclusive to certain choices.

Introduce branching paths that respond to player choices, allowing the narrative to evolve in multiple directions. For instance, in World War 0x, players could choose between various maps and game modes, each leading to different experience and outcomes.

Branching paths can significantly influence your open-world experience. A common issue in many modern open-world games is the use of pseudo-branches. These are instances where players are given "multiple options," but all choices ultimately lead to the same outcome. What truly makes a branching path compelling is the butterfly effect that one decision can have, altering the world around the player. NPCs notice your actions, the landscape changes, factions rise and fall, or even small moments like saving a dying child who later becomes a high noble. However, not all decisions need to be grand and far-reaching; some can be simple yet hard to find, adding depth and subtlety to the narrative.

Por exemplo, em um RPG, a escolha do jogador de salvar um NPC de um ataque de bandidos poderia abrir um caminho de miss?es secundárias com esse personagem, aprofundando a rela??o do jogador com aquele NPC e desbloqueando um final único. No entanto, essa escolha também poderia fazer com que os bandidos guardassem rancor, impactando outros eventos futuros no jogo e limitando outros caminhos ou finais.

When a game offers players significant choices and executes them well, it enhances the gaming experience, especially in storytelling. The key is proper implementation. Many games allow choices like saving or abandoning a character but fail to show real consequences, reverting to the status quo. For impact, a choice must affect the character's development and influence their thoughts and actions moving forward. In the Metro Exodus series, the protagonist initially dismisses the deaths caused by his actions, but as the series progresses, these choices begin to weigh on him, altering his interactions and personal growth, and making the narrative more engaging.

Characters should react to player actions in ways that feel natural and impactful. When I worked on creating NPC behaviors, I used state machines in Unity to ensure characters remembered player interactions and adjusted their behavior accordingly. For example, an NPC who was wronged by the player might become an antagonist, altering the storyline and fostering a more dynamic, believable world.

While making an open-world game, it is better to create a side character that will accompany the player during gameplay. This helps keep the player engaged, as the dialogues between the main character and the side character can be very enjoyable to listen to. For example, games like The Last of Us and Uncharted are great examples of this.

Um ótimo exemplo disso é a série Shadow of the Colossus. Ao derrotar cada Colosso, Wander (o protagonista) sofre consequências físicas e emocionais, impactando diretamente a narrativa e a jogabilidade. Essa rela??o causa-efeito entre a??es e o desenvolvimento do personagem intensifica o peso moral das decis?es do jogador, criando uma experiência memorável e emocionalmente carregada.

NPCs are the lifeblood of many open worlds. As humans, we are social creatures, and having something in the world to interact with enhances our immersion into a game. NPCs are an open world's way of literally talking to the player, informing them of their progress and the impact they have had so far. Some open worlds suffer from a distinct lack of NPCs, making the few interactions all the more special. That moment when you feel lost and unsure of where to go, only to be reassured by a bombastic NPC who becomes your lifelong friend, is a truly special experience.

NPCs that react to players significantly enhance a game world's realism, as seen in Elden Ring, where each NPC has a unique personality, backstory, and ambitions, enriching interactions even with bosses. However, vibrant worlds aren't solely dependent on NPCs. Journey exemplifies this with minimal text; its storytelling is conveyed through environmental design. The desert landscape not only tells its own history but also emotionally engages players, demonstrating that a game's setting can effectively narrate and complement traditional NPC-driven storytelling.

Allow the game world itself to evolve based on player decisions. This can be achieved through environmental changes, altered NPC populations, or accessible areas. In one of my previous projects, Scooby Doo Funfair Scare, players' choices in interacting with hidden foods and special keys affected the game's progress and experience, such as player's score, health and new levels progression. Using Unity’s scripting capabilities, these changes were reflected in real-time, making the world feel responsive and alive.

How can you talk about an open world without discussing, well, the world itself? Nothing breaks immersion more than a static world that never changes. That's not how our real world works, and it shouldn't be the case in an open-world game either. The world should constantly evolve based on the player's decisions. It should start off small when they begin their adventure, but as they progress, the player should feel like a master of fate, able to turn the tides of war or shape entire regions to their liking. The sense of accomplishment and power when you feel like you have conquered and transformed the world is a profoundly satisfying experience.

Excelente ponto sobre a evolu??o do mundo nos jogos! Um exemplo adicional seria em um RPG, onde a escolha do jogador por ajudar uma vila de fazendeiros contra ataques de goblins pode, a longo prazo, fortalecer a regi?o, desbloquear miss?es com NPCs gratos e até mesmo influenciar a economia local com o aumento da produ??o agrícola. Já ignorar o pedido de socorro pode levar à ruína da vila, gerar um ponto de propaga??o de monstros no mapa e até mesmo fechar caminhos antes acessíveis. Essa persistência nas consequências torna cada decis?o impactante e contribui para a imers?o do jogador.

When a player takes over a new area or gains new abilities in a game, it should really feel like a big deal. In the game Ghost of Tsushima, when you free a village from enemies, you can see the village come back to life. People start working, shops open up, and kids play around. This makes the player want to save more areas. The villagers thank the player by giving them special deals, gifts, and new tools. When the player visits the village again, the people there thank them and celebrate their return. This makes each victory in the game feel important and rewarding.

In the dynamic realm of open-world games, quests serve as the lifeblood that propels the narrative and immerses players in a richly woven tapestry of choices and outcomes. The true magic of these quests lies not merely in their completion but in the profound impact of player decisions on the game world.

Who doesn't love a good quest? How many times have you heard someone rave about the depth of a certain quest or how unbelievable its twists and turns were in an open-world game? Quests provide direction in open worlds, guiding players to explore and discover places they might have otherwise missed. However, it's crucial to be mindful when designing quests. The reward at the end must be worth the player's effort. If even one quest offers lackluster rewards, it can deter players from accepting future quests. A good quest enhances the world, while a bad one detracts from it.

Imagine um jogo onde você precisa ajudar fazendeiros que sofrem com bandidos. Completar a miss?o com combate gera recompensas imediatas, mas aumenta a hostilidade na regi?o, levando a pre?os maiores na loja local e tornando outros NPCs mais desconfiados. Já optar por uma solu??o pacífica, como negociar com os bandidos ou ajudar os fazendeiros a construir defesas, pode trazer recompensas menores a curto prazo. Entretanto, a longo prazo, gera uma economia local mais próspera, NPCs mais amigáveis e até novas miss?es ligadas à prosperidade da regi?o.

Quest consequences are one of my personal favorite ways to get a player immersed into the game they are playing. An example of this done based on a reputation system (or, more aptly, approval) is one of my most played game series, Dragon Age. Depending on what you say in conversations to NPCs or how you choose to resolve quests or even which quests you choose to complete (or not) will affect your companion's feelings towards you. Certain events may even bring about a companion leaving for good. This makes the play a more immersive experience by having the player really think about what their companions are like and how they will react to different situations, just as one might do to their friends, colleagues, or associates in real life.

Everything should have an impact to the story. If you choose a track than it should have consequences! That’s what makes it feel real

Customize the narrative to reflect individual player experiences. This involves tracking player statistics and preferences to tailor the story. For example, incorporating a system that monitors player choices and generates unique content can make each playthrough unique. In Love Diana Dressup, we implemented a system where players' in-app purchases and challenge completions shaped their narrative, providing a personalized gaming experience.

Implementing systems that track and respond to player behavior creates a personalized and immersive experience, allowing the narrative to adapt dynamically to individual decisions. This not only enhances player engagement but also encourages multiple playthroughs to explore different narrative outcomes.

Give players the freedom to explore, experiment, and make their own choices without heavy-handed guidance. Avoid linear progression and allow players to tackle objectives in their own way. Provide multiple solutions to problems, encouraging players to find creative approaches.

Allowing players to view the consequences of their actions will make the experience more dynamic, as if the game itself is also a player. This extra freedom will encourage players to replay the game, making new choices they otherwise wouldn't have their first time around simply to see what would happen.

If you are making an open-world game, it is a nice touch to include NPCs in the game. Players always enjoy listening to their dialogues, especially playful ones like jokes.

Um ótimo exemplo de ciclo de feedback eficaz em jogos é a saga The Witcher 3. Uma decis?o tomada no Ato 1, como salvar ou n?o um certo personagem secundário, pode ter consequências significativas na trama principal e até mesmo influenciar o destino de reinos inteiros mais adiante no jogo. Essa interconex?o entre escolhas e consequências, especialmente quando reveladas de forma gradual, refor?a a sensa??o de impacto do jogador no mundo e o impele a ponderar cuidadosamente cada decis?o.

One of the biggest questions in a player's mind, whether consciously or unconsciously, "What will happen when I do this?" Effective feedback will answer that question every time it comes up, so take the time to make that answer reasonable. Think of what could happen to the plot, the characters, the environment, the game's progression, and possibly even the mechanics after the player makes one amazing success or one grave mistake.

Environmental storytelling is an important element to consider in open-world games as well. A clever application of the Disneyland weenie concept involves strategically placing points of interest on the map to guide players through the environment. Excellent uses of this concept can be seen in games like “Half-Life 2” with the Citadel (though not an open-world game), and “Zelda: Breath of the Wild” with Hyrule Castle. In both cases, these prominent landmarks are visible from various parts of the map, effectively drawing player attention and naturally helping to shape the narrative as players explore the world.

You need to ask yourself, "Does this game I am making really need to be open world, or am I just following a trend?" Just like how not every movie needs to be an action movie, not every game needs to be open world. While an amazing open world experience can draw someone in and transport them to another world, a bad open world experience can easily break suspension of disbelief and cause someone to put down your game, even if everything else is perfect.

I always look at game development as dreams coming true. You dream in your mind and make it real in life (at least in the 2D/3D world). This has always motivated me in this industry

A very interesting but still in-beta way is to embed AIGC API into the game and let them be the characters, which will make it much more flexible (e.g. the player can type their own words in daily chat with NPCs rather than choose between options). And we still use numerical values in detecting the progress and letting them influence the fixed main stories. While challenges remain in ensuring quality and managing player’s input diversity, related new tech is developing fast and the potential benefits are immense.

A few more things that can help the design of the game. Embrace failure as a catalyst for growth and compelling stories. Welcome ambiguity to deepen player engagement and spark discussion. Continually test and iterate based on player feedback to craft an organic and fulfilling narrative.
