Coming in to fill another spot in the "pony games comprised entirely of OCs" lineup (which seems to be getting distressingly popular as of late) is a project by the name of Adventures in Equica: Unicorn Quest. The developer, Yotes Games, describes the project as an action-RPG, with a battle system reminiscent of top-down shooters and exploration similar to 2D Zelda titles. The game is still in the conceptual phase at the moment, unfortunately, but the developer promises daily updates for those of you who are interested in the development process. You can read more about the project, including the developer's long-winded explanations of various game concepts, in this post on his blog.

Personally, I'm interested to see how far this project goes; while anyone can write up a pie-in-the-sky game concept without necessarily being able to bring it to fruition, the developer already has some completed projects outside of ponies under his belt, which gives me some confidence for his. Plus, there seems to be a lack of Android pony games that aren't just ports of Flash minigames or clones of other, more popular mobile games; this project has a chance to please that under-served niche in the
fandom.
