And by the way, here's a Shenmue character model upscaled to HD:
Maybe it's just me then, but I find the character models from METAL GEAR better even if those pics don't do them justice. SHENMUE goes more for the more colorful, easy going anime-ish look.
Also, I think that Shenfa model is different from the ones in-game. She never appears in-game only in those few couple of movies.
Plus SHENMUE had plenty of technical hiccups, like in-game loading and null draw distance. Chararters would disappear and appear just a couple of steps away from you.
In any case, for the original question of the theard that if the PS2 was really stronger, there's very little doubt in my mind that the PS2 it was a stronger and more capable system that DC. There's a lot of games besides METAL GEAR bear significant proof.
Even the NAOMI arcade board required to be upgraded upon and thus there were many games that SEGA wasn't able to convert to the DC.
