Oh gosh I'd love this. X-Men are my favourite favourite heroes. My most precious thing (with apologies to my cat) is my X-men 2 film cell with the scene in the mansion where Wolverine touches the ice wall...I have that piece of film reel framed in my display cabinet.
I don't have werewolves and vampires so I don't know what actions they can carry out, like flying or whatever. I didn't add them because I don't want that element in my game. I've never liked those characters, except for watching Twilight mostly on fast forward or from behind a chair. I love Star Wars but I haven't added that because I just find it a bit random as a world and would have preferred a separate game for it.
They could even just do a costume collab to get the suits. But it's two massive corporations and a lot of licensing, etc. I don't know if they could, but then I didn't think they could do it with Star Wars and they did. But how cool would it be if our Sims could be heroes! They could add it as a personality trait or a reward trait, or part of the Scientific career. I have my Strangerville and my Scientists linked so why not Superheroes.
I have a celebrity Sim who wears a disguise and rescues strays at night but that's the closest I've got to a hero(she's a celeb villain during the day).
My Sims Cosplay at the Geek.con but it could use some variety as a lot of NPCs wear the same costumes.
Oh now I'm dreaming of a Wolverine Sim, I'm so devoted to him I even bought his Broadway soundtrack 😳.
