The game is already really good and fun to play when it has some really good tunes being severed along with it! Mastering the whole combo system is easily one of the funniest things you can do!
Imo it was kinda groundbreaking for its time. I loved showing off smash and playing it with my friends in middle school a lot. It also introduced tons of cool characters and I loved the dlc returns!
The only fun i got from this game came from the dlcs i regret buying because i really wanted to hear the og soundtrack and play as silly sega characters
