I have only made it through act 2 out of I don't know. I still feel ok calling this a 5 out of 5. I could stop playing it right now after the 6ish hours of the best arcade racer I have ever touched. That's on race and car feel alone. The sense of speed, the feeling of the boost, the underhanded tactics shown in episode one are played out with an amazing token system. The token and build system captures the feel of a season of racing and on an on and on.
The only knock I might end up making against this game is variety in biomes or race modes or multiplayer. I have not engaged with any of that or felt it out. This review is to say that is 6 hours of the campaign mode you will have a 5 star experience and everything else is gravy.
