This game is hands-down the best sports game ever made, for any console. It has a save feature, season, preseason, playoffs, Super Bowls, Pro Bowls, and the like. I highly suggest you pick up this game, as it will provide you with hours of playing fun!
Challenge: B+. Piece o' cake at first, but boy, the playoff and the Super Bowls will make you work.
Graphics: B-. The zoomed out view makes it tough to judge the graphics, but the closeups and cut scenes are awesome.
Sound: A. Tecmo has a rep for having good music, and I'd say it's the best of any Tecmo game. There's different music for the playoffs, regular season, Pro Bowl, and so on.
Fun: A. Trying to win with shitty teams always provides a burst of amusement, and destroying the shitty ones is even better.
Overall: A+. Hands down the best, and that's all there is to it.
