@anon_mastermindOh damn, Wii Remote Pluses.
I was actually rather drawn to this version purely for WM+ Tennis. Forgot I don't have that many WM+ enabled controllers though. One attachement with Resort, and the Skyward Sword Wiimote+. I think I got a third WM+ with Red Steel 2, but I lent that to a friend when he borrowed Skyward Sword. Must get that back.
Dad's got his attachment from his copy of resort...that makes 3. Will have to do.
And yeah, I think there was a retail release. Never did look at it too closely.
