Mass Effect was fun but main story line was sub-par. I beat the game thinking I was only half way through. Wasn't impressed with the sub plots, whereas oblivion had good sub plots but not a good main story line. Haven't gotten into this game yet busy with GOW2 and still have to beat Dead Space. Fallout 1 & 2 were my favorite games of all time though. Should rent a PS3 and beat Metal Gear 4, really is a perfect game.
