1. The binding of isaac... fuck me this is getting ridiculous, this has got to be my 10-11th playthrough, and i STILL can't get past the depths. Its those jumping headless things, they're an absolute ***** to kill. Especially when they jump across the entire room and land on you. An absolute blast though, i can't stop playing it. Even if it does just punch me in the gut then piss on me. For £3 it's a shameful amount of fun.
2. Minecraft, just the free browser thing, but it's still fun.
3. Oblivion, getting in a few hours before skyrim.
4. err... black ops?
