First off, forgive me if I'm double posting here. I have no way to searching the forum.
The creativity of what is being shared here is impressive. I would like to be able to read the ratings left by other users a bit easier. I'm sure they're accessible somewhere other than the Feed page. Whether they are or not, it would be nice if the full rating text was displayed on the game view template somewhere.
The rating text is probably the most important asset these developers have. Psychologically they will always be more effective than comments. Ratings sell.
I would venture that you could drop the comments plugin altogether and allow others to reply to the ratings posted. Nothing new here though, that is pretty much industry standard these days.
