Im a bit annoyed with the wii points system to be honest. Before the Wii came out and information was only just starting to come up, there was a rumor going around that once you finish a game, you get a certain amount of wii points depending on how hard the game is. That would of been so much better then having to buy the wii points then buy the games on your wii.
I think it should be something like you earn 1000 wii points for completing a hard wii game like Zelda twilight princess, and 500 points for beating an easier game. Its kind of stooped down to microsofts point basis. I doubt it would severely effect the sales in a negative way to at least try it, and I'm sure a lot more people would want to buy a Wii if that point system was around. It kind of pissed me of when I went onto the wii store for the first time and it came up with " Pay this amount of money for the wii points". Kind of takes the fun out of it.
