Ekaiyo is a fan-created pokemon MMORPG project. It’s still in early stages, even though they’ve put lots of work into it. There is no playable version available yet, but if this project gets finalised, then it will certainly be one of the most unique and populair Pokemon MMORPGs. because unlike the others, this game will offer a 3D rendered world and characters.
You might want to keep an eye out for this game, I know I will.
