I'm mostly doing RPG so
-Final Fantasy VIII (PC)
Awesome game, Awesome story, Awesome animations (for that time of the game), nice graphics, Awesome music
-Fable
Like the aging part of the game and aside from the hack and slash the game is quite fun
-Oblivion
Great Graphics, if you add up the side quests to the main quest you get a lot of hours to play the game+shutting down all Oblivion gates, the side quests + main quest is quite fun to play
-Jade Empire
also a great game I just bought it so i can't tell much, but I like the fighting styles+the graphics are quite nice and the quests are fun too.
-Vampire the Masquerade Redemption + Bloodlines
Both games are great, the graphics of bloodlines use the HL2 engine wich is quite nice
both have great story and Bloodlines have nice side quests.
Now on the MMORPG section i deffinetly have to go with GuildWars cuz it's the only MMORPG that I played for 700+ houres (don't mind Xfire cuz I downed Xfire one year after I started playing GW)
I played WoW but it couldn't appeal me now i got LOTR online so i'm still registering so dunno yet!
