Everyone should post what they've been playing recently. Especially the lurkers.
I've been playing the Battlefield: Bad Company beta (as you well know), and have been loving it. I also just beat Army of Two a couple of days ago. I tried playing co-op with my wife, but that was worse than an escort quest in a game with bad AI, so I had to kick her off. I've been playing the single player campaign of Rainbow Six: Vegas on the PC, and of course I'm still playing good ol' Oblivion. On the DS, I've been mostly playing Professor Layton and the Curious Village, and on XBLA, Puzzle Quest. When the CoD4 map pack gets released (today or tomorrow) I'll be playing more of that again. I recently beat Condemned: Criminal Origins to get up to speed and play (the apparently superior) Condemned 2. And come Saturday, I'll probably be playing Space Ace, which I should be receiving from Netflix. Oh, and can't forget Smash Bros. Brawl!
My wife has been playing a lot of DS lately, as she recently beat Dragon Quest Monsters: Rocket Slime and Zelda: Phantom Hourglass (which I haven't even beaten yet).
So what have you been playing?
