I've been playing a Japanese copy with an English patch for a few weeks now. It's Pokemon, same as ever.

Some of the designs are...odd. There is a trash bag pokemon named Trubbish. It's description is something along the lines of "a trash bag exposed to radioactive waste." It's evolution is Garbador, and it is a large pile of trash that has broken through the trash bag that was formerly Trubbish.
