Perhaps the PS2 era coincided with a time in my life where I didn't care as much for video games as I did for surfing the internet and hanging out with college friends. Of the ones DM listed, I only played the FF and KH titles. I eventually played the remastered GoW series on PS3 and did like it, though.

That era just seems like the awkward teenage years of gaming. Sony broke into the market with PS1 and was the cool new kid on the block, but I just don't think PS2's lineup was better than PS1's. There's nothing close to a FFVII or Symphony of the Night on that system that made me awestruck. KH is the closest it came. For Nintendo, it was their first attempt at disc-based games and it seemed like they were still trying to figure out ways to evolve and react to Sony's insurgence. Other than Metroid Prime, the GameCube didn't produce anything groundbreaking. Wind Waker is underrated though.

I think a lot of it depends on what you grew up with. Obviously a kid born in the 2000s isn't going to say NES was their favorite era, or even PS2/GC.
