On top of the fact it's phenomenally animated, it also plays well. The game has a lot of cool mobility options which never cease your ability to use an attack. In that sense, the game is really fast and encourages a lot of rush down even with zoners. There's a lot of crazy ways to mix up pressure and the lack of air combos makes it so that aerials are more valuable for granting knockdowns, which is a neat dynamic. The defensive mechanics also provide interesting ways to deal with pressure.
