I first got this game for the Nintendo DS and I later got it for the Wii. I enjoyed the Wii version much more, but the DS version had easier gameplay.
The DS version of the game is a side-scrolling platformer, and it is very fun. However, it is ridiculously easy and it only takes two and a half or three hours to complete. It also leaves out an entire level that is only available on the big consoles and the graphics leave something to be desired. But overall, it was pretty fun, even though I beat it who knows how many times.
The Wii version is much more challenging. I've had it for a while and I haven't been able to complete it yet. The bad thing about the big console versions is that the camera is terrible and sometimes it is impossible to play. The camera adjuster was mapped to the +Control Pad, which is at the very top of the Wii remote and is rather hard to reach while beating up enemies. The gameplay was not very easy as you can tell that the game was not designed for a Wii remote and nunchuk. It is still very fun and it includes the level that was left out in the DS version. It also has many more cut-scenes than the DS version.
Overall, the DS version is the most limited version of The Simpsons Game. If you want to play the complete full version, you should get it for the PlayStation 3 or the Xbox 360. The Wii version is still brilliant, though. This game is amazing and any Simpsons fan will love it.
