I've gone back to Portal 2 as it's been long enough that I've forgotten some of the puzzles. I've also started to play the co-op mode as well, which is just as good. Such an amazing game, maybe top 10 of all-time for me.
And thanks for the reassurance on Far Cry 3, Pete. I was pretty much set on getting it anyways. I actually got completely bored with Far Cry 2 and didn't get far into it, but I'm confident this will be a lot better.
Anyone play Journey? Looks pretty amazing and it won a bunch of awards. It's supposed to be really short but it's only $15 or something.
