You play Binary Domain yet Oscar? I finished it the weekend, was really good :3
On the topic of modding, the only way it will really work on GAF is if
a) GAF becomes a smaller community again
b) GAF moderation is transparent and appeal-able. What I always did was make a section where only banned members and mods can post and through this you can explain your workings to the community member plus give him a chance to explain himself/argue his innocence. The totalitarian bullshit GAF has going is pretty much the antithesis of functional community moderation
