This is a game I didn’t know existed until a few years ago, when I saw a video somebody had made using it on Youtube. I looked it up on eBay and was way overpriced; most of the listings being for the disc only, not the original packaging.
Without particularly trying, I managed to find it for £1, complete with original box.
The game itself is pretty good, it’s easy to use and there are plenty of animations and sound clips of each character to choose from. The sound clips can’t really be strung together though, which makes for some quite random cartoons! Also there can only be one speech, one music, and one sound effect playing at one time, so there are pauses between characters speaking. The animations available are mostly of the Simpsons themselves – the secondary characters only have a couple of animations.
