Pokemon Reborn is probably one of the greatest fan-made Pokemon games I've ever played.
I cannot stress enough how cool this game is.
It's got all Pokemon and will include the new gen Pokemon AND HAS FULL ONLINE FUNCTIONALITY.
The story is also something else entirely, it's much more dark than the cannon Pokemon games but it's intense as hell.
