Club is my favorite Wii Sports game, and the least popular. How can you become a competitor?

First, Wii Us can have their regions changed with Accounts. You can get a Japanese Wii U (the cheapest) and put a gaijin Mii on it (unless you don't want to and prefer Japanese). Digital is faster and cheaper. Get 2 Wii Remote Pluses and a GamePad Charger that plugs into the Wii U. 32GB is faster than 8GB and slightly more expensive. No particular region is faster. No particular color is faster. No particular year (2012-2016) is faster.

I did a bit of testing myself, and I was unable to find proof that digital is faster than physical. It is possible that it may load slightly faster, but it is not significant. About half a second is lost across an 18 hole run by playing physical compared to digital.
