List Your Pack Ideas Here!

What about a pack where your Sims got to be superheroes? I've been getting really into the MCU and a tabletop RPG called Masks lately, and as a consequence superheroes have been on my mind a lot. The pack could come with some kid of ultra-metropolitan city with superheroes and supervillains. Sims could have different powers, or be civilians out of their depth who want to stop the villains anyway. Maybe it could lend itself well to some kind of story-based gameplay like StrangerVille offered. What do you think?
