I know AI disclosure is optional for games, but the first thing I do when I look at a game page is to look for the AI disclosure, and if it doesn't say that no generative AI was used, I move on. Refusing to disclose that you use AI isn't going to make me give your game a chance, and refusing to disclose that you didn't use AI is just going to scare away potential players/customers.
Please fill out the AI disclosure on all projects you upload, regardless of type. It's for you own benefit, as well as the benefit of everyone who comes to your project page.
