So, I am finally going to break down and attempt a family story...

Naw, they aren't hard to make.

Usually, it's just normal gameplay.  You can plan what's gonna happen or you can go by what happens. 

You just take pictures of what will be interesting or good for your story, and make a story out of the pictures.

I sometimes plan, then I sometimes don't plan.  It would be easier if you plan, but unplanned gameplay allows for some surprises.  Then you can make a planned script or whatever out of it.

They aren't hard to keep updating, it depends on how much freetime you have.  Some people update almost everyday, some do it once a week.

And it's up to you to wait till TS3.  Though, if you do it now, you may get practice for TS3, and will know more about it when it comes out.

And yeah, go ahead and try one!
