If I were Nintendo I would make up a new character that is a Mii everyone could make and slowly introduce him in this game, and then in subsequent releases the game would be named after this character.
I think your close than you think, because i feel that's already been done...... lets examine this point here....
The three biggest selling games of all time are Wii Sports, Wii Play, and Wii Fit. Wii Sports Resort and Wii Fit Plus are well on their way to join them (as both have sold more than 12 million copies).
I don't think this is a sign of running out of ideas. This actually seems like a natural extension of the Wii series and Miis, I am surprised they waited this long to do it.
They have given us the new charter already........US, instead of giving us the lovable look(more Mushroom Kingdom) and sound of Mario(Wahooo!) , they give us these representations of us that ushers the
immersed feeling of you in the game. When the pack in of
Wii Sports came along we said "hey they could have made this
Mario Party Wii", and the same for
Wii Play. If all of the Games that TJ Spyke mentioned was Mario spin offs, we'd be pretty piss at the moment.
Sorry Ian Sane, Mop it up..............Yes, WE love Mario, but more Wii owners love Mii.......
