When a game designer's project faces scope changes, they should first communicate openly with the client. They need to reassess priorities and identify core features that align with the client's vision. It's crucial to manage expectations by clearly explaining the impact of changes on timelines and resources. The designer should propose alternative solutions or scaled-down versions of features to maintain the project's essence. They should also document all changes and agreements to ensure transparency (In the GDD and all other relevant documents). Flexibility and problem-solving skills are key in adapting to new scope while still delivering a quality product.

Communication is your best ally. First, gather your team and assess the impact of the changes—then, engage with the client. Be transparent about what’s feasible within the new parameters and adjust timelines if necessary. It’s like recalibrating a game’s difficulty; you want to ensure it remains challenging yet enjoyable. Prioritize key features that align with the client’s vision and keep them in the loop throughout the process. After all, if you’re going to level up your project, you want your client to feel like they’re getting a bonus quest, not an unexpected game over!
