Although I've got some other stuff I'm playing, I'm focusing mostly on Fallout: New Vegas. I like this a lot more than when I first played it on PS3 and I'm not sure why. Before I believed Fallout 3 was the better game, but now I think I prefer New Vegas. Maybe I just like them equally and both have their pros and cons with something about them that makes them feel very different.
Another game I'm playing is Dishonored for the second time, but I've lent it out to a couple friends and one of them has it at the moment so I won't continue that for a little while. There's also Hitman: Blood Money, which I never played before and I'm not sure why. I guess I would have bought it sooner if it wasn't so difficult for me to find a 360 copy; it's an awesome game. I'm also just on chapter 3 of Halo CE Anniversary even though I rented it a really long time ago. It's good, but I never played the first game much so it doesn't have that nostalgic value for me and at the moment New Vegas is a lot more fun. I'm also a decent ways through The Darkness 2, but it's not really fun so I'm not playing it much, and also Fable II, but I won't be returning to that for a while because I've already played it enough before and I have other things to do. Eventually I want to get the DLC and play through the whole game as a good character.
Also played the XCOM: EU demo. I liked it a lot more than I thought so I'll be looking to buy that when it drops in price; probably on Boxing Day.
