I've been concentrating on Mass Effect 3 lately. There's a lot of stuff in this game. I've finished most of the base game now, maybe 80% if I had to guess, as well as the Leviathan post-release DLC module, and am currently in the middle of another, Omega. After that there is the final DLC, Citadel, to do, along with progressing through to the end of the campaign against the Reapers.
I've been mostly sticking to the renegade option, but going with the paragon one with Shepard's close friends when that seemed appropriate. Garrus, Liara, Ashley, and Tali from past games have all joined the crew, along with EDI, Javik, and James. Mordin, Thane, and Legion all gave their lives to the struggle, while Jack, Jacob, Grunt, Wrex, Miranda, Morinth, Kasumi, and Zaeed are all out there doing various things, as far as I know.
Elsewhere, I've been running the Spelunky daily challenge again, looking forward to wasting some time on that during my upcoming Japan trip. I also played around with Super Crate Box on the PC for a bit. I'd played the un-controllable iOS version before, but it was awful to grapple with sans buttons. With a proper man-machine interface, though, it's good fun.
