A pokemon mmo!
This one has actually been out for a couple years, and while it's still in "beta", the team working on it has ramped up their efforts lately.
Plus sides:
- Sprites and gameplay like fire red and leaf green!
- Kanto AND Johto
- You can have any pokemon follow you!
- It's a ******** pokemon mmo!
Negatives:
- Battle system not fully implemented (no special/physical split, status effects other than poison don't work, most moves that aren't purely attacking fail...)
- Small server capacity (they're working on a new server)
- Lots of random down times
Something tells me that if they can keep it up, in 2 years this will be one hell of a game, and everyone here will wish they had played through at least the first 8 gyms before it got uber popular.
