Poor Billy. Poor, sad, Billy. Poor, sad, lonely, Billy.  Poor, sad, lonely, depressed, Billy.  Poor, sad, - okay I think you got it.  I regret to inform you, dear reader, that there appears to be a shortage of co-op game releases this week.  And by shortage, I mean none.  Even the XBLA and PSN have let us down.  So what's a gamer to do?

You could always start up a new character in one of your favorite games.  Or you could get started on your backlog.  Finished your backlog?  Are you sure?  Maybe you missed something.  A lot of great co-op games came out this fall.  Here's a list of all the retail co-op titles that have come out since September 6th.  Feel free to add any retail co-op games I may have missed in the comments section. I'll post the downloadable titles soon. Probably next week. Probably...
