Is this real? I guess it is. The folks have actually gone and tried to make a Pokemon MMO, and they’ve… sort of succeeded! PokeMMO is a fan made MMORPG based in the Pokemon universe, and you can play it right now. Until Nintendo do something about it.
It looks really interesting, but after a quick search I haven’t found any information on precisely how the developers are allowed to do this or if they’re allowed to do this. A couple of years ago Nintendo closed down the very similar Pokenet, so you would imagine it’ll only be a matter of time before the all-seeing eye of Nintendo/Sauron bears down upon this cool little program with the legal force of Perry Mason on red cordial.
So you might as well enjoy it while it lasts. You can head here for more info and download the program while you’re at it.
