Tomodachi Life: Living the Dream has a demo out now, and players are already using it to create absolutely ridiculous Miis and throw them into silly situations. But a word of caution if you're playing the demo yourself: don't play too much. If you get too far into the demo, eventually all your Miis will lock themselves in their houses and only robotically talk about buying the full version.
There is a way around this: simply don't create that third Mii. Once you create that third Mii, you're set on a forced track to the end of the demo, even if you try to avoid building the clothing store afterward. But if you never make the third Mii, it seems you can keep playing the demo infinitely, though that does mean you never get to make more than two Miis or dress your Miis up until the full game comes out in April.
