Great game. Good Multiplayer. Does nothing oustanding, but everything well.
Fantastic in multiplayer (especially in wireless if you like trash-talking :)), and suprisingly well balanced. My friends and I could try practically any combination of heroes without running into one that was overpowering.
The number of different characters that comes along throughout the game makes for good diversity and I never got stuck on a particular level.
Overall, I highly recommend it, especially considering how few and far between really good DS games are. Compares favorably to other turn-based game I'v tried.
