Not long after Questria's developers decided to unponify their game it seems that the folks behind Pony Tactics: Salvation decided to do the same, and have renamed their project to Spectrum Tactics. To be honest I'm not really surprised with their decision, but hopefully most other fangame developers will keep their spirits up and continue working on their own projects. After all, so far Hasbro has only C&D'd fangames that either had My Little Pony in the title or whose developers contacted them for permission (such as the poor soul who created Equestria Tales).
The original announcement can be found here, in case you want to read it. Cheerio!
