Unfortunately the engine is not for Pokemon, as it is designed for 3D; although it could possibly be used to make a Pokemon Colosseum-esque game.
Ironically though, some of the first test-models I used were maps that were ripped from Diamond :)
Actually, I've had an idea for this game for some time now, but every time I make significant progress, something comes up that greatly impedes the effort - like Microsoft axing future support for indies on the Xbox360. The amount of work required to make EVERYTHING for a game is indeed eye opening; I have many pages of code with literary thousands of lines, and models and textures that I've spent weeks making. Despite all the work involved in a project like this, I still find it very fun.
So what kind of project - I would suppose a ROM hack - are you working on?
