What is the best free online pokemon game?

I seem to get a lot of comments asking "what's the best free online Pokemon game", "what's a great online Pokemon game", "what online Pokemon MMORPG is the best to play" ... stuff like that.
To be honest I have played a whole heap of them and they are are kind of the same, they most be or they would not be a Pokemon game. What sets the good games and bad games apart is the small things that make a huge difference - things like speed of the site, how often the servers are offline, how many members play. Like all games, the littles things matter.

The best of the best free online Pokemon was / is Pokemon Crater
But there are plenty of others to try out, just go through this site and I am sure you will find one.
Here are a couple to read about . Pokemon Indigo and Pokemon Mystery Dungeon online MMORPG

Some Pokemon games have not been updated for ages but are still playable other games are updated but are not quite good enough still. I know the games are free and made by fans but you still want one that is fun to play, fast, and has enough online players to play against. Enjoy.

Pokemon Mystery Dungeon Online Free MMORPG

Pokemon Mystery Dungeon Online is looking like it will be a really good free Pokemon game to play online (of course it's online, it's in the name :) ).
I have read that the free game developers at Pokemon Mystery Universe are developing a Pokemon Mystery Dungeon style MMORPG that will be free of course. They are a small but friendly community of fans so it looks like a game to look out for.

The game has seven different Base Type Pokemon to choose from when you begin your game. The seven are Grass, Fire, Water, Normal, Electric, Psychic and Ground. As an egg you enter different paths to decide which Pokemon you want to be. All Pokemon have some type of special ability, such as walking through fire. They say some abilities haven't been decided yet but the game is just starting so it will come.
Like I said a good free Pokemon Mystery Dungeon Online mmorpg game to watch.
