I am new here so I don't know if this is possible already and i somehow missed it, but it would be cool to be able to request games to release here on itch.io. 

Hey there,

This is quite a difficult feature to implement. If you’d like to see a game on Itch.io, you can contact the developers of that game and ask them about it.

That’s my personal opinion, the admins might have a different view on this.

Hope that makes sense :)
