I use it, but the amount of stars you get per game is so low that it doesn't really make me more likely to get a Nintendo game when I want a new game.
Also, they won't ship physical goodies to Norway, so I only get Wii points. Not that it matters, the only other thing on there I would be interested in is the SNES classical controller - that thing is hawt.
I do have 2000 stars at current, which trades for 500 Wii points, so the question is whether to spend them on a NES game, or wait for another 1200 stars and get a SNES game instead. Decisions... Decisions...
You must get many more stars per game than we get coins per game.
