Although it lets you wander around a game board and participate in various multiplayer challenges as your favorite Crash Bandicoot characters, the game ultimately crashes and burns because the majority of its minigames are lifeless and uninteresting.
Crash Boom Bang is a mess. There are too many unneeded features, not enough time was spent developing the important ones, and hundreds of small hiccups and issues make this game feel like it should have gone through more inspections at every level of design.
Crash! Boom! Bang! looks good, sounds pretty okay, and has had a decent amount of focus put into the multiplayer support of the Nintendo DS. It's just a terrible, terrible game with poor organization...Easily one of the worst games on the system.
