What is the most impressive 1st generation game for any system ever? It doesn't have to be an initial release but something that came out relatively close to the American or Euro release of the system like within a year.

I can't really think of anything except maybe Soul Caliber on the Dreamcast. There's been plenty of games that I was amazed by at the time but looking back, not so good. I'm not a big audio guy so nothing sticks out as far as music either.
