I haven't played Wii Play so I'm mainly going by it's reviews. But I'll comment on Wii Sports, I love the game, and I'll ignore how shallow it is and the fact that it lacks depth and gives single players little reason to keep coming back for more. It's great for parties and such, but my real complaint is the gameplay, particularly the boxing controls are aweful. They don't pick up very well. and the baseball controls should have a little more depth especially to the picthing. the standards of the tennis and bowling are way higher and in my opinion and they are the less popular video game sports. it's easy to give the game a free pass being that it's the first of it's kind, but if you translated these sloppy gameplay mechanics to the latest zelda game people would lose it.
I didn't mention it earlier because I know the game was free with the system so I don't want to complain about something free. My point is nintendo's standard's are clearly higher for second party western developed titles, then they are for party/casual games. And again I'm not refering to depth, I realize very clearly that the casual market actually doesn't want depth, but they do want simple intuitive gameplay with responsive controls.
