Yup, i played Mass Effect 2 on the PS3 - which included the graphic novel of the first game. It was amazing for the first 2/3rds but then got somewhat repetitive and was anticlimactic.... with that said, im really looking forward to the 3rd one.
I played Fallout 3 on the PC and for some reason just couldnt get into it, and i spent a good 10 hours on it... I liked it, but the whole "everything is destroyed" theme wasnt that fun for me after a few hours. Too much gray and brown. I know its a good game, just not for me.
