There are also a lot of differences. I could go on for hours talking about the differences in these two games and giving you different details. This is something I have no intention on doing. If you want to know all that is different, I suggest you rent both and play them for yourself. I will tell you what the main differences are and which one is better.
Graphics are a very important part of a sports video game.
They have also become more and more important over the last 5 years. Great graphics have become almost too important, with some companies sacrificing the gameplay for good graphics. That is a different argument for a different day. 98 are the best graphics ever seen in a sports game, period. Acclaim uses the hi-resolution mode on the N64 to produce graphic and smooth animation that I thought any home gaming console could not accomplish.
