Yeah, I'm inclined to agree with you... it's rather weak. It's like a Pokemon Box that tries to hide it with a flashy world that's incredibly limited.
I loved the thought of it when I first saw Ranch, myself... then I looked more into it and saw that there was hardly anything to do. Sorry, but a $10 game that's nothing more than the "show me this Pokemon!" minigames from GSC and RSE doesn't strike my fancy.
