Game-makers don't care about about AP. They want their games to be played, and having a high rating makes them happy. Low ratings show that they need to improve their games. Anyways, game-makers already get 20 AP for submitting a game. And I don't think any have complained to want some more.
on top of what firetail just said,if the developers really did want AP then this could easily be manipulated(even if it is highly unlikely) for the fact that any member can rate a game,such as ghost accounts for instance(fake accounts pretty much).So since it doesn't seem the developers want AP....yet and this could be manipulated,and I'm sure there could be plenty of other reasons why this could not work,then I don't see this as something that AG could use.In other words it just won't work.Sorry if it feels like I'm shooting your idea down(which I kind of am truthfully)but almost every idea has its cons,and this one has too many that I can see just within a few minutes,and that is why I don't think it would work,much less be considered.Also on top of that I believe many other similar ideas have been suggested and shot down before.
