Honestly People are complaining so much about alot of stuff and tbh I don't get why, Sakurai gave us all our old favorites Inklings, Ridley, Chrom, Dark Samus, Daisy, king K Rool, Isabelle, Ken, Incineroar, and a pirahnna plant (which prove you don't even need to be a main rep to get in to smash bros), plus 5 more characters
15 new characters...only 2 less than smash 4
Along with, Stage swapping, obstacle toggling, smash meter, training, squad strike, iron man,lobbies, music, customized online matches, spirits mode chalenges, and a full voice acted story mode
Along with most reps we wanted who didn't get in are stil represented in game in some way
Honestly this is what happens when you hype up a leak as much as this one people bought so much into it that of course the end result isn't going to matchup to expectation
