First of all, if you have never seen the Animaniacs you need to rent, download or whatever and watch at least several episodes before playing the game. Animaniacs was to me, the last cartoon series that really carried on the spirit of the older Bugs Bunny cartoons. The Animaniacs are awesome.
So the show is great, how is the game? Well, first of all there were two much different versions of the game. There was one version for the Super Nintendo and another for the Sega Genesis and Game Boy. Both were fairly typical side-scrolling 2D platform games but most everything else about the games was different.
The Genesis version came out about a month earlier than the Super Nintendo version in May 1994. It had excellent cartoony graphics and a plot that involved the Warner siblings (Yakko, Wakko, and Dot – the stars of the show) exploring various movie sets in Warner Bros. studios looking for items to sell in their new shop. However, once these items are collected, Pinky and the Brain (two white mice) steal them in order to take over the world (an ongoing theme of the show). The player must complete four levels (in any order) and then a fifth level where Pinky and the Brain must be fought. Each Warner sibling has their own special abilities. Graphics, gameplay were both good and the game did a good job of expressing the spirit of the show.
