Excite Truck actually was fun, like Hydro Thunder on wheels. This, however, looks fucking stupid. That's not to say that I never thought Excite Truck looked generic--it DOES look generic, but it also has an appreciable sense of speed and the super-sensitive tilt controls somehow made tree runs much more enjoyable.
EDIT: I think I just found out why I thought Excite Truck was so fun: scoring points for tree runs and truck smashes. There was something spectacularly satisfying about getting a 5-star rating for both. Oh yeah, and the terramorphing was pretty cool too. Every race was stupidly chaotic and the original buttrock soundtrack suited the game well.
