YOUR Help is Needed!!!!... WE Are Building A Game

What if YOU could help decide how a video game is made from scratch? Rules: 1) Have a game without needing new content or updates to be replayable. 2) Minimal external assets usage. 3) AI cannot be used to generate anything for me (only used as a substitute for google if used) 4) Must listen to the most voted idea in the comments. Thank you and God bless!!
