Yeah, it DID have six face buttons, and also more niche 3rd party games than the GC did, even though it was based on expensive cartridges, hilariously enough.
I mean, if Rush, Mace: The Dark Age, Beetle Adventure Racing, NBA Hangtime, Hexen, BattleTanx and Fighter's Destiny came out last week, they probably would have been PS2 exclusive. Sure, none of them are Zelda or GTA3, but they were fun, filled out my library, and also help me make my point, I think.
