i just got God of War, it is the most amazing game i have ever played on all of my platforms being, ps3, gba, n64, wii, 360 (i play ps2 games on my PS3). the graphics are great, the combat system is great, the story is great, the whole layout of the game is AMAZING. way better than i thought it was going to be. and i already thought it was going to be the most amazing game on the PS2, but it is way better. 
god of war 2 is more amazing than the first one. the graphics are better, the story is better, the gameplay is all around better, there are more puzzles that are more puzzling (sorry about my bad grammer), there are more bosses, i could just go on and on about how much better the game is. The world is more vast, the characters are great, the greek mythology (though probobly not accurate) are great. sorry i just cant stop talking about how much better this game is than the first one.
