Also on March 27, 2013, the Skullgirls Indiegogo campaign raised $725,000 USD, allowing Mane6 use of that game's engine for free. To that end, Lauren Faust herself has joined the Mane6 team to design all-new characters. On March 2nd of 2013, Mane6 revealed that, although their efforts to get special permission from Hasbro to continue the game have met with nothing but dead ends, they still plan to finish the game in a different form (but retaining all of the game mechanics). Production was halted on February 8th 2013 due to a cease and desist order from Hasbro, while Mane6 attempted legal negotiations. A state-of-the-state overview of the game can be found here.
There is a forum discussion about it (and Them's Fightin' Herds) here. The final version of the game was to feature 17 characters. It featured characters from the first season of the TV series My Little Pony: Friendship Is Magic. My Little Pony: Fighting is Magic was a fanmade Fighting Game being developed by Mane6.
