Easy to get started... Lots of fun.
Excite Truck is a great game for young children because it doesn't require many precise, controlled movements. Half of the fun in the game is leaving the track to earn stars for tree runs, huge jumps, and crashes.
Although I have not looked closely, I cannot see any human drivers in the game. The cartoon-like scenery and the physics-defying motion also serve to tell kids that this is a game, not a simulation of real life. Because of this, I would not have described the game as "violent".
