This game is the cheapest childcare service you will ever buy, bar none. Kids dig it. Its basically the closest thing to a child-friendly GTA that you can get.
The real kicker though is that two kids can play simultaneously in split screen. Absolutely marvellous. Saves so many fights.
Might buy a second copy, love how great it is to share games across consoles - except if you have digital and both kids want to play at the same time.
