Why did the Gamecube fail?

[Leynos]

PS2 despite more raw power than even Dreamcast. It was a difficult machine to work on and even had some limitations where even Dreamcast did things better. Why PS2 textures look so blurry. DC was very good at that. PS2 also had no AA but DC did. But raw polygon power PS2 outclassed it. Not saying it doesn't exist. Not found a PS2 game pushing more than 6MPPS. Where the highest found in Gamecube so far in what I've seen is 9MPPS with Rogue II. Dunno on Xbox. Not seen it tested where I look.

Gamecube, Xbox and DC were easier to develop for than PS2. A contrast from the PS1 being the easiest of it's generation.
