Alright, Nintendo doing a game on WiiWare is good considering how it's basically been a 3rd party service for the most part. My only real problem with this (besides the ludicrous story, which is standard fare for Nintendo really) is that note about the Wii Zapper. I have to wonder how stupid they think the general public is (obviously, quite a lot), because just about every game on the Wii that doesn't require the classic controller supports the Wii Zapper. It's a frickin' plastic shell that has no impact on the game's functionality whatsoever! I'm surprised they didn't put "supports the Wii Zapper!" on the back of the Smash Bros. Brawl box, because it would be just as relevant.
Now, if they said "optimized for the Wii Zapper", that would actually mean something. That would mean that the controls have been configured in such a way that if you're fool enough to use the Wii Zapper instead of something like the Nyko Perfect Shot, you could actually have a fun time.
