Individual games can have a subforum of sorts, in that you can enable comments on them (I haven't done this though, as I don't want an additional place to maintain)
It'd be cool to split those forums up like Steam does, at least with General Discussion, Bug Reports, and Announcements areas. This way they'd feel less like a generic comments section on a news post and more like a dedicated hub of discussion on your project.
Yeah personally I was thinking of a Steam like system for forums for games. The comments thread for a game isn't really a good place for engagement (particularly since nobody even seems to use it?).
It'd be nice. The reason I keep being hesitant to activate comments on my games (though I begrudgingly do) is because I know they're just going to turn into flame-wars and I'll have to shut them off again. A little organization should help alleviate that a bit.
