Post any areas you get completed in the comments, so they can be looked over.
Sinnoh will be harder to lay out than Hoenn, due to Mt Coronet, and the 3D nature of the game. And it'll probably be me I am laying out the region's foundations. Region is layed out, few areas need bits added, and interiors need to be done.
I'll have to do I have done the snow routes. Mojang screwed up snow cover...Interiors will be done at the end, as will the town/city embellishing.Interiors added, those should be all of them. If you want to do one, ask me and I'll clear out land and set command block warps between them.
