I have an upcoming Mobile Game Design course for my Junior year at the Pennsylvania College of Technology and the project I'll be working on is this Pokemon style game featuring ponies. The Ponymon Dawn/Dusk ROM hacks inspired me to tackle turn-based combat, multiplayer networking, and fixing everything that bugs me about the main Pokemon games (mainly the grinding and brainless AI). There are only mock-up images right now but I'll be putting out calls for pre-alpha testers once something actually exists in Unity.
Development is off to a good start and things are becoming clear as the design document gets filled in. Of course I took a couple days off for Christmas with family, but got right back into development and I'm about 50% done with the game design document now. I should be nearly finished with it by next week so I can start drafting ideas for ponies and tweaking the document for game balance. Things like items, moves, and abilities will be planned out once I have a set number of pony designs and I know their strengths and weaknesses.
Get a bunch of sales data from my other games and a list of progress for Battle Gem Ponies on the developer blog.
Good luck!
