There's oodles of great games on the PS3 and Xbox360 console :-)
I picked up Dungeon Siege for $1 at the dollar store. It isnt too bad and its great for a dollar. I just remember playing Desert Combat with everyone and having a blast. Oh the good ol' days...
In relation to PS3 games, a majority of them support mouse and keyboard support so it get's the goofy controller out of your hand. And if you think about it, if your patient enough using a controller really isn't that awful. Just think of how great of an experience Dead Rising is on the Xbox360 and what your missing out on with just that game alone Squid.
Plus there is Left 4 Dead right around the corner. I think that's a Xbox360 and PC title.
