I think that having a Favourite Game Developer section of your page would be a great feature. It would make it easier to check new releases give the developers more exposure. I think that anyone should be added (from thier profile and from in a game) and it would be good that someone who is second or farthher down on the game credits list should have the game on thier page and be able to be added. Also I think that there should be a group chat (join a group, like in games) and a privet chat- two people talking, with the option to set if you are busy, away, avalible, appear offline or whatever. Also-ontop of that idea- if someone has not done anything for 30 minutes they have another option set on avalibility on chat.
Thank you, I hope that you like my ideas. (Sorry if this has already been suggested. :( )
