There's also ' PonyKart', which was abandoned by its original developers and is currently in development limbo.
The whole pony-in-socks thing still throws me for a loop, though. Not only does it look a lot more like the show, it also seems faster paced and has a main character that doesn't look terrible. If someone wants to try a simple, but functional MLP fan game, try the fantastically titled ' Horse Game'. Not to mention all the legal trouble this/these folks could get into with Hasbro for using their designs. And it doesn't look like the show at all, there's way too much detail. It's like one of those thousands of terrible OCs you can make with the Pony Generator. This one? Lighting seems alright, the graphics are acceptable, but I cannot help but feel like this is mostly just a pet project that got way out of hand.
