Pokemon Type: Wild
Pokemon Type: Wild is a fan-made fighting game where Pokemon duke it out, Street Fighter style, which is a far cry from the turn-based [strike:2sikjyb7]posing[/strike:2sikjyb7] fighting that we're usually familiar with when it comes to Pokemon battles.
It's unlicensed though, and the first time I saw it I thought it would never last--yet it's been around for several years and is now on its 4th iteration for Windows PCs. I've always been impressed with the way it looks, with excellent animation; Nintendo & the Pokemon Company should take the cue from these guys and turn it into a full game.
