it was well known fact xbox was strongest console last gen so not sure why people keep arguing about gamecube being more stronger because it is lies and even devs can back it up
Let me say this once again today: The Xbox is still the most powerful game machine on the planet. Not only is this the greatest compliment that a software engineer can give to a piece of hardware, it is also a reflection of our appreciation of the Xbox for allowing us to run DOA3, DOAX, and now Ninja Gaiden with the quality that we, Team Ninja, hoped for.

My first thoughts were, what can we do with this game on Xbox that the other consoles couldn`t? So we focused on an increased number of polygons, multitexturing, and designs to exploit the hardware.

The number of textures, visual effects and polygons we throw onto the screen would bring any other console to its knees. We really made the most of what the Xbox offers a game developer.

The hard drive for streaming, pixel shaders for some effects, and the raw power. It would not fit on a PlayStation and would change beyond recognition to fit the GameCube. It's not that we've been inefficient either; we're just asking a lot of the hardware, and the Xbox is the only one that can deliver.

Both the GameCube and Xbox are clearly superior to the PS2 in terms of the quality of the graphics seen in games available today. The transition from PS2 to GameCube and/or Xbox is a fairly large leap, but going between GameCube and Xbox is a bit less dramatic.
