Since we are now in the middle of the 360/PS3/Wii generation, enough time has passed to look back at the PS2/Xbox/Gamecube generation in retrospect. (Wiki lists these as the seventh and sixth generations of games consoles).
Many of the games that were favorites at the time have been superceded by newer and better games (often the latest versions of their own series), while others continue to stand as very good games. (I'm leaving out PC games, as it's much harder to pin down generations with PC games).
So, looking back, what were your top games of the sixth generations of video games?
Halo 2 - Cheaper, out earlier, more games. These were just some of the reasons that I didn't buy a 360 for (despite being true when I was getting it). The main reason was that at some point in the future, Halo 3 would be on. And Halo 2 was a brilliant game. Excellent story, brilliant soundtrack, online play that "just worked", graphics that could compete with a lot of the early 360/PS3 games and a good story. Halo 3 didn't live up to it's expectations however (thank god COD4 and Final Fantasy XIII are multi-platform, or I'd have to buy a PS3).
Final Fantasy X - There seems to be a pattern forming where the best Final Fantasy games are the first in their generation. VII, X and (if the previews are anything to judge by) soon to be XIII are some of the best Final Fantasy games in the series. They each had huge revolutions (to 3D, to spoken dialogue and realistic graphics, and to um... even better graphics).
Kingdom Hearts II - In the first game, the mix of Disney and Final Fantasy did not really work that well (everytime Donald spoke you wanted to blast him with Fire), and the story was poor, but the combat system (a mix of hack and slash, and traditional final fantasy combat values) was cool. The second game, was a good bit darker and with a much heavier Final Fantasy influence. And they manage to turn it's biggest weakness into one of it's strengths. Just imagine Donald Duck fighting alongside Cloud and Squall. It's hard not to laugh.
