Well...they made fluid animations for 649 Pokemon, plus additional forms. That's probably around 10 sprites per Pokemon each, if not more. That's well over the number of sprites I would expect ANYONE to make, and Game Freak goes and does it for Pokemon B/W. I think it's easy to forgive them if the shading is a little shoddy. :/
okay what's next.. toaster.. anyone....
Garbage bag Pokémon in a region that's based on America. What's that supposed to mean?
