I am currently developing a game called Pokemon Online. The official website is Pokémon Online - Home. It's a free Pokemon MMORPG which will be based off the original games. It's still in early development, but you can download POL v0.5 to test the online engine out.
Here are some preview screenshots of v0.6 (still to be released):
