Personally, Mario games are my favorites. I like Mario Kart, New Super Mario Bros., and all the sports games. People like Mario as a character, I guess, mostly because of the familiarity. But, another reason people may like Mario is just because, with the exception of his usual catch phrases, he doesn't say anything at all. That leaves a lot to the imagination about his character, and adds a whole new dimension to his games. I don't know, that's just my say.
