As some of you may know, there is an upcoming fan made fighting game based on MLP:FiM, known as MLP: Fighting is Magic. We don't know a whole lot at this point, the developers are being kinda secretive, all we really know is that the mane 6 will be in the game, and more ponies will be added later (but they won't tell us which ones), we have no release date (other than telling us "soon"), it WILL be playable online, and that thus far they have only really finished (or nearly finished) Twilight Sparkle and Apple Jack (but it's implied that they have finished other ones, they just aren't telling us). The updates we get are few and far between, but we do now know that there will be voice actors (fan voice actors, not pros) for all the characters (or at the very least for the mane 6). From what they HAVE shown us, it looks very well done, it looks good, and looks like it has nice fast paced gameplay, and from a programmer's perspective, it looks very impressive.
They did a livestream about a month ago in which we got to see Applejack VS Twilight Sparkle, here's the links:
