Rogue Leader, Metroid Prime and
F-Zero GX. All pushing graphics and visual effects and
all running at 60fps as well.
Since we are cherry-picking, there's Resident Evil 4 which, on the PS2, was a significant visual downgrade VS the Gamecube original.
This is true.
Halo is pushing larger environments, sure, but generally they look empty. This is especially bad in indoor areas of the game because you get very large, flat surfaces. Thankfully, the bump mapping does give some depth but it's not as good as having better geometry detail:
Metroid Prime has smaller sized areas but they are so much more detailed, with high geometry detail, making everything pop. Even cracks on walls are rendered with geometry. Sure, there is no bump mapping but because you have so much more geometry, with so many 3D elements to catch your eye, it's not as needed.
And of course, you also have the higher frame rate on top of that.
I always thought Metroid Prime is a much more impressive game than Halo because of these reasons.
