I picked up civ5 a few days ago + Castle Crashers a few weeks ago and I'm waiting until I have more money in steam to buy anything else (I believe I'm getting steam money for Christmas).
I have most things I want atm, but if some stuff goes on sale significantly I'll probably buy them. Depending on the money I get I'm looking at XCOM, anno 2070, Rome 2 and Dark Souls 2.
