Download & More Info

I downloaded it a while ago, it's alright.. But there's some major laggage, and I'm pretty sure it's not just my computer.. But otherwise it's pretty good.. It does get annoying occasionally when you're trying to go into another area (yeah, they have to have transitions between towns and paths, etc.) and it's lagging that bad, that it wont let you.... Give it a go, good for a little bit of fun.

Oh my dear Jehovah God? My dream come true?!

NO!!! dont touch it... take it from me who has played all the online pokemon games i could find... dont touch it...

It's not bad, really side_scroll'r. as it's still in development, it still has room for improvement... However, the thing I find frustrating, is the amount of people that look like you that are wandering around in the long grass.... It's like a damn hall of mirrors.

Looks like they're in need of character customization...

They should at least implement different colored caps.

Well apparently there was one in development, I don't know whether it's been cancelled or it's been taken down temporarily for further development, but it had customisation.. You could choose your gender, cloths colours and patterns, etc.

yeah it was still in development 2 years ago when i tried it... doesnt seem to have gone anywhere... ; ; it is sad... i wish they would make an official pokemon mmo.

Well apparently there was one under development a while ago that pwned, but wasn't official.. But it apparently got shut down by the powers that be.

hmm... ill probably just wait till its final lol. but the one i played you couldnt even catch pokemon cause they didnt put that in the game, you just bought them... it was pretty lame. and everyone looked like you lol.
