Remember that wonderful Sesame Street x Street Fighter crossover art series from way back in 2010? Artist gavacho13 made a pretty funny spoof, and now after all this time it's been turned into an actual game.
It's not quite a fighting game in the traditional terms. Sesame Street Fighter is more like Typing of the Dead in that you have to type out words to fight your opponents. So there's an educational angle still there at least.
