My 8 nieces and nephews under 14 are all devoted Sims players. I can hardly wait to find out if they know about SimSlice -- and what they think of it. My guess, based on the thumbnails included with the story is that they are all going to be (or already are) madly enthusiastic. The Nesting Dolls notion is a fun metaphor to bring to it, but I think it doesn't look closely enough at the material textuality issues going on here. Anyhow, off to play a little of it myself...
