I'm sure the Wii had a few shooting games (like Link's Crossbow Training), but I'm not sure they would be classed as shooting gallery games. They're definitely in the same vein and a Wii should cheap to pick up now. You'd probably also be able to homebrew it for most other shooting gallery games (There's even a homebrew port of Duck hunt as there was never an official release on the Wii virtual console)

House of the Dead: Overkill is excellent. Not for kids but that's the point.
