I think when it is a bunch of people who know what they are doing, I don't really care. But if it is a game that requires some finesse in the menu navigation and set-up and such, it makes sense for the person who knows what they are doing to be player one. Of course, in New Super Mario Bros. Wii my nieces and nephews often fight over who gets to be what character, and if someone wants to be Mario they kind of have to be player one.
