Not too long ago, Actxyn began releasing information about an RPG that he's working on in Flash. The RPG has a typical turn based RPG battle system, much like that of the Final Fantasy series. The game does not have that much information released to the public yet, but the creator is looking for people to join the team, and some music bronies to make him some sweet tunes, or allow access to their existing ones.
If you are looking to help out, you can check out actxyn's DeviantArt page HERE, and send him a message.
Below are the two current videos showing what the game has so far. You can also check out his DeviantArt for some more screen shots.
