I'm sorry man, the results of their color depth choice produced some absolutely awful artifacts that mar the visuals at poitns. During the industrial areas, for instance, ENTIRE SECTIONS are coated in nasty, flashing bands of akwards colors.
No matter the detail of the room, when you have walls with this all over it (and mind you, it is not a static side effect; it moves and jitters all over the place in dark corners)...
It really does affect the final product.
I don't want to sound too harsh here, though, as RE4 easily stands as one of the most impressive looking games I've ever seen. I absolutely adore the game. When wondering how hard they pushed the hardware, I was not implying that they weren't pushing the hardware so much as I was wondering if it would have been possible to render in 24-bit instead. The game is a visual masterpiece, I'm not denying that, but the particular flaws present DO drive me crazy. I return Warrior Within GC for the same problems, for example. It's not a minor problem (though its impact is decreased quite a bit when viewed on a standard analog set). I feel sorry for VGA box users...
