I'm strictly a PC gamer. I love Team Fortress 2, Portal 1 and 2 and Left 4 Dead 1 and 2. I like Battlefield 3, just hate the interface.
But I can't play any of these (except Portal 1) without being in a Skype call with friends. It's more of a social interaction than just playing video games.
If anyone is interested in playing any of these together PM us and we can exchange Steam names.
