Count me in! Just an idea, but if your project will rely so heavily on the comunity you could make like a point and click adventure or something like that about the comunity itself. The youtube comenters can be characters and you can even ask them how their characters would react in certain situations. Also if you are planning to use a community of developers like itch.io you can hide some easter eggs of the projects people are working on too. I think that would be fun and will attract more people.
Again, its just an idea so regardles you use it or not you can still count me in the community, it sounds fun!
