It certainly does make me think a Sim can die during a magic trick. I'm thinking something like a trick with swords that goes horribly wrong. It's a real life magic trick, not a fantasy magic trick. There's a contortionist in those boxes and if she doesn't contort the right way at the right time, the sword could do terrible things.
I think the expansion pack looks fun. It's going to bring a whole new experience to the game. I think I'll like it.
