(So, here’s a suggestion, add more things to do once you’re bored with the game)
once you have unlocked all the cars/tokens and crushers, got max car and all badges (most or what badges you can get yourself), it gets pretty boring afterwards even the derby gets boring once you got the 100 wins badge and left with nothing to do.
this is why I stopped playing because of the grinding just to get a badge that will probably be lost in your roblox profile page after awhile
