Little off topic, the new source game where up to 4players have to co-op against masses of zombies or something looks good, thats my type of game! We dont need single player anymore, they need to start making true co-op experiences, after all, we generally all do have internet connections. Itll be much more fun working out puzzles designed for multiple people to take part in, aswell as having to communicate with each other employing tactics to survive etc.
Thats the way we should be heading!!!
