Depends on what you're looking for, if you're like me and the only modes you play are training mode and versus mode, then it's worth it, plus I wanted all the gougi cause the standard ones weren't doing it for me
But yeah the base game is low on single player content, no story mode, no arcade mode, don't think u can unlock colors other than buying them with real money
They're slowly fixing this though, they recently added arcade mode and they'll be more down the line
