Why do people dig up this past artifact!? aight, Mine is Fallout 3, ME 1/2, and Oblivion are kickass RPGs. These are probably the games that have kept me most entertained for the longest time. But, I'd have to say that even though i always go back to playing those just to keep me occupied and happy, shorter games (you know, the ones you don't put at least about 50 hours into if you wanna do most everything) are shooters with great multiplayer and stories, Bioshock 2, MW2, Halo 3. Though, it is always hard for me to choose between long term RPGs and games known for a great online experience and shooting..
My favorite games are: 1.Fallout series 2.Bioware games(Mass Effect,Dragon Age and others) 3.Metro 2033 4.Call of Duty Series 5.The Sims series 6.StarCraft series
