I'll get more into Hatsworth later, but TrackMania's draw, for me, is the customization. Really dig the handling of the car used in Stadium races? Use the in-game credits to get more Stadium action and ignore the others. Like Platform, the challenge of avoiding holes and having enough speed to make the jumps? Just play that to unlock more.

There's a lot to choose from, including the option to make your own tracks, but what's available is up to you. That freedom, not being forced to partake in the portions you don't enjoy as much, that's a nice shift from the linear "do all this to advance" mentality.
