I couldn't resist -- I had to buy it. From what I remember, and keep in mind I haven't played the game in a long time, it looks almost identical. The game is SUPER fun to play using the Wii Remote + Nunchuk. Also, the game is WAY easier, since you can actually choose a difficulty. I remember the Dreamcast version being way too difficult to the point that it became no fun.
I thought about busting out my DC for comparison, but eh.... What's been said is true: smooth framerate and nice controls :) I remembered this game being outrageously good looking back in the day, heh... Not so much now. But still, can't wait to get further in and jog my memory a bit more! --- Pudding: It wiggles and jiggles.
It certainly looks better and smoother. That and the difficulty selection, make me think it's actually a port of the PC version. But... did they cut the music tracks in half? That sucks. The soundtrack was awesome.
The one in the video just fades and restarts after less than two minutes. Now to be honest, I don't really remember if they were actually cut in half in the PC game too, though i doubt it. I should check it. Wonder if my copy still works on Windows 7?
