The second step is to define your portfolio goals. This will help you decide which game mechanics to include, how to organize them, and how to highlight their value. For instance, you may want to demonstrate your creativity and originality by including unique, surprising, or experimental game mechanics that you created. You can also showcase your skills and expertise by including well-designed, tested, and refined game mechanics that you implemented using certain tools, frameworks, or methodologies. Additionally, you may want to match the expectations and needs of your audience by including relevant, appropriate, and appealing game mechanics that you tailored for specific genres, platforms, or markets. Explain how you came up with the game mechanics, what inspired you, what challenges you faced, what feedback or metrics you used to evaluate them, and how you researched or analyzed them for the target users.
