ME1 is a bitter pill to swallow. The game is OK, but too long with the planet mechanics. If you REALLY like the ME universe it might be worth it to experience a lot of the small decisions the comics gloss over.
Im currently still working through ME3. I was hoping to work through Tuchanka but havent had enough time.
Im looking at picking up Demon Souls once im done ME3 and wrap up Skyrim. Demon Souls or Alan Wake.
I am not sure i want to play Diablo 3 but my bro got it for me in May for my bday. I like Diablo but ive never been a fanboy. Usually fizzle after a week or so.
