Sure, Excite Truck isn't the biggest game ever, but it delivers high speed thrills and excellently designed tracks, plus it has that Nintendo magic. Getting an S rank on every track is gonna take some time. Multiplayer is also great fun on it, there is a drop in frame rate in this mode though, but its still cool.
There are loads of new trucks to unlock and they do handle differently. The sense of speed in the single player mode is really good too, with some nice motion blur effects. The game even allows for custom soundtracks.
