get Umbrella chronicles.... the life is shared so you can rock the game and she won't die next to you ^^
and it works as a horror movie type thing... you could play close to each other :p
(it's a rail shooter)
(my favorite moment was when I had my gf scream "yes!!! ..... oh no, it's disgusting I blew his head off, i'm a horrible person now :(" (that was actually in gears 2, but she liked umbrella.))
