Ooh, that actually sounds quite interesting - taking a place that some Sims would know and having it desolate and deserted. Really, I think any Sims location would work if you are going to do that - it is just picking from the various options! :D

I saw you mention a worry about portraying the violence and blood. I'm not really sure what options are out there for violence and posing. I've seen a few pose boxes, but I guess you could just show parts of a sim, and describe the violence. Or close shots of arms, weapons and that sort of thing to portray the violence.

I'm really excited to see this - even if it doesn't follow the book/movie/manga it is an awesome idea to put the Sims teens in that kind of situation. LOL, I just have an image of Tank/Ripp/Buck standing up and saying, "But our Dad is in the army! He wouldn't let us be chosen!" XD
