Of course not. I said if that was your priority, I could see choosing PS2. Or if you only play JRPGs. But if you care about a broad range of genres, it'd be hard for me to see picking it.
I dunno, that's a pretty narrow way to look at the PS2's offerings.
I think the PS2's catalog of 3D platformers is fuggin'
unreal compared to the DC, Xbox, and (surprisingly) the GameCube. Same with survival horror, racing, character action, and some unique stuff like Shadow of The Colossus, Twisted Metal: Black, Ico, Mister Mosquito, Gitaroo Man, Katamari, etc.
For platformers, you got
several trilogies of stellar platformers on the PS2. I don't know if I can name any on the original Xbox off the top of my head, and I certainly couldn't point back to Sonic Adventure as a genre staple. Subjective, I know, but I think it's fair to say the PS2's 3D platformer offerings best the other consoles combined, unless you're REALLY into Mario Sunshine?
The PlayStation 2 library is as diverse as games get.
