There are some small features I wish had made a return, but with how robust this one is, it's hard to really count those against it. Endless fighters with the spirit system(which fits in well thematically to the game's meta premise) and solid feeling arena fighting, a compelling story mode, lots of customization. It's hard to imagine a much better SSB than this. 2024 edit: I spent some of the vacation where I proposed to my wife playing this on a ship and I view that as a fond gaming memory
