Recently...
Max Payne 3
I enjoyed playing through Dishonored and you can't really argue with Half-Life 1 & 2. Grand Theft Auto IV is way too much fun. I also really liked the newest installment of Tomb Raider.
I really loved Bastion, its one of those games that i had gotten hyped for and it did not disappoint.
The bioshock series is really amazing too. I played the first one and fell in love, however i did not play the second one untill I finished Infinite, but all three have so much replay vaule in my eyes.
Games of note
KingdomHearts 1&2
Psychonauts
Sleeping dogs
Ratchet and Clank games (really just the first 2, everything from 3 and onward was kinda eh, but still enjoyable at times)
Jack and Daxter games
Saints row 3
I'll second Uncharted 2, I wish I could play it on my PC.
FF7&8, Legend of Zelda: OOT, MM & WW, Soul Reaver, Mario Sunshine, Hexen, Final Doom plenty of others but i'm not too into single player anyhow but to pick one probably Castlevania SOTN!
Real Life..Man it can be so difficult..Anyone have some cheat codes?.lol Really though maybe the old megaman's or shining force..
couple 2 players I liked..
my most favorite 2d figther was..Guilty Gear
I also liked Elemental Gearbolt..I use to play it in what I called deaf mode and turned of the sfx and left the music..It was so great at the time..man hallucinogens
People have pretty much mentioned everything, except for one... How has no one mentioned Red Dead Redemption?
Because it is a console exclusive, I am actually pretty upset that it isn't on PC. That game is actually my favorite console exclusive next to Gears of War 1 and Halo 3.
