Except Mario is the first thing you think of when someone brings up Mario, his name is kind of in the title. What's the first thing you think of when you hear Wii Sports? Sports. Over time, Mario became a well liked character in a series of games that were fun, yes, you could apply this to the Miis, but everyone here is saying that Miis are inevitable because they are already said, iconic characters. They aren't iconic though, the only reason you all instantly think of Miis is because "That bro got four characters out of six right so far, and there's no way he could have guessed the Wii Fit Trainer, prepare yourselves for Miis!" Yes, as Neon said, maybe some people picked up the games because of Miis, but are you both really going to argue that the minority who bought it because of that reason mean that Miis are iconic? If that's the case, then Geno must be super iconic because he had a small cult following. Then again, apples and oranges. Ask the average Joe who's played Wii Sports what he remembered the most from it, do you honestly think he'll say "Well the Miis of course!" if anything, he'll say something about the motion controls.
Again, apples to oranges. The majority of people who buy those games don't care who or what they're playing as, they did actually buy those games because they could wave their arms around like idiots, that was one of the major points of the commercials. Do you think old people, parents, and casuals in general are just going to buy a game because they like Miis? Or because they can go bowling in their living room? The same applies to Wii Music, people wanted to make music.
