I don't play any other games except DM at the moment (if i did, i would have no time for real life ) , so i just gonna say what games i really liked before^^
Gothic 1 (2001) and 2 (2003) :really great games (they are a bit in the style of Oblivion, but Gothic 1 and 2 have something Oblivion does not have... i call it "soul").. i played Gothic 3 too, but i was disappointed...Gothic 3 was more like Oblivion- imo it lost its "soul"
Max Payne 1 and 2 (2001 and ..2004 i think): 3rd-person-shooters wich one of the greatest storys in a shooter ever, and the inventor of bullet-time (slowmotion) in games
The Hitman games (played it until Blood Money) : i rly liked them... i loved to stay "undercover".. and in the right moment, the sniper rifle comes out of the bag...
The Chronicles of Riddick:Escape from Butcher Bay (2004): this game is a blockbuster. amazing story,atmosphere and cutscenes; the coolest hero in a game ever and the gameplay is good ,too
Medieval 2 and Rome : i like the scenario and the epic battles
GUN(2005): a kind of GTH (grand theft horse) in the wild wild west! good story and atmosphere; the prove that good atmosphere does not need good graphics
Command and Conquer: Red Alert 2 (2000): The gameplay was not that blanced, but i really liked it. Great cutscenes! I had to laugh so much when i watched them
Flatout 2 : a nice fun racer; nothing special, but it makes...fun
Quite old games, but really good ones
Btw, if anyone wanna play a bit Unreal Tournament 2004 of Flatout 2 online together with me, say it^^
