I'm currently juggling around a lot of games, which can be a real pain. At the moment I'm playing:
Oblivion - Halfway through the Dark Brotherhood missions, and mostly ignoring the main storyline xD
Minecraft - Dominating single player, as usual - oh wait no, I take that back. My last 'amazing' maneuver involved a bridge in the Nether and a horde of Zombie Pigmen pushing me off it into lava D:
Mass Effect 1 - Haven't had the chance to play much of this at all, I'm still wandering around Noveria killing SPACE LOBSTERS.
Devil May Cry 4 - My friend reccomended this to me, as it contained a separate storyline to the other DMC games, but it's becoming pretty hard.
Team Fortress2 - MY FISTS, THEY ARE MADE OF STEEL(In other words, still maining Heavy and taking names)!
Killing Floor - Another great game for Steam, shame my connections taken a turn for the worse and my ping has made the game pretty difficult to play :|
Pokemon Emerald - My favourite game in the Pokemon series. Playing it again because it's fantastic.
Soon I'll be playing Skyward sword and Skyrim, two LEGIT GAMES DAWG - I just wish Christmas would hurry up so I could play 'em.
