Basically smash 4 but they improved upon it in every single way. This game is basically a wonderful tribute to all things gaming, as it has so many characters from so many significant series in it. The spirits certainly weren't as interesting as trophies were but they still do a decent job with archiving game characters throughout history. The game also added a ton of highly-fan-requested characters so it feels like a love letter to the fans as well. My only problem is that smash 4 burnt me out on the series too much for me to really embrace this game as much as I definitely should have. It's still a great time to play with friends though so definitely get this game if you have a switch.
