Platforms in preparation for Showtime/bands?

I don't think that was the main intention, considering platforms are really important for creating the kind of architecture they were looking for in this pack and not having sims interact between platforms would have greatly slowed the game. Still, I do hope they take this as an occasion for creating stages. (And yeah, I did think about that and perk up when it was mentioned during the stream.) I'd love to see a band focused pack with sims actually singing and playing music together.
