And believe me, I am hardly a graphics whore, but I do have standards, and I know Nintendo can make very good looking games. OoT was great looking in its day. WW is still astounding and unique looking. TP is, at best, extremely uneven. I expect Nintendo's flagship titles to be the best looking on their systems, and TP doesn't even stack up as an impressive looking GC game.
TP was a far too ambitious game to do justice on last gen hardware.
Although I think TP is a fuck awesome game, and I do think it looks beautiful at many parts, there are some very uneven areas.
By the way, Nintendo's teams have never really been top tier with their graphics from a technical perspective (unless you count Retro, I suppose).
