No worries mate 
I don’t think it’s clearly written anywhere, it’s more like guidelines designed to maximize everyone’s forum experience, if you want to see a good example of how to make a great project topic, I can recommend having a look at the LitRPG topic where @PaulBellow shares his experience of developing a video game using AI.
In any case I will be looking forward to reading updates from you, I think your project is very interesting!
