While Madden 2000 looked like it was trying to revitalise the series, Madden 2001 just comes across as a more clinical version, with the smooth white UI still used today, and less focus on the silly elements (although some of the silly teams are still here). I also suspect that the bigger focus for Madden 2001 went towards the PlayStation 2 version, with the N64 version being seen as less important.

Fine

Remake or remaster?

The genre has evolved.

Official ways to get the game.

There is no official way to play Madden NFL 2001.
