It's not going to give you a minecart section every three levels, if you're into that sort of thing.But won't it get super repetitive fighting 1200 fights ? It's like challenge mode right ? Or mortal Kombat tower
Smash is, regardless, inherently more varied than a typical fighting game due to functional differences between stages and game directed hazards and item spawning. All of this is drastically driven down in tournament settings, and in local play there's much arguments about what is fun and what isn't, but if you're playing by yourself you can dose these things according to your tastes.
