Spin-offs (Nintendo Miis)
Machinima-like techniques are being used to create tutorials for making “miis” . . . . What is most interesting to me, though, is the interview-based style of the tutorial. They don’t SAY anything about “here’s how to do it” . . . they SHOW how to do it, they keep the pacing brisk, and then the interview track provides almost metacontent and commentary via an interview format. It is really quite clever when you actually think about what they are doing/accomplishing. It also says a TON about the learning and thinking styles of 21st Century kids.
Contrast that with the official Mii advertisement/tutorial.
And contrast Second Life with Mii Parade.
Even business people like to play!
