Agreed. If you can get two separate sides to work together to do this, there's really no way to stop it. Moreover, I'm sure this is a rare occurrence and there's much better things for the dev team to be focused on than trying to figure out a way to combat this.
My choice as well, it's a perfect setting for it. Hell you could even make it a two-fer game with you starting in Revolutionary US and then going to France.
That first part with the burning buildings, casino/neon lights, the shipwrecked boat, reminds me a lot of the Fallout 3 expansion where you go to New Orleans.
@QualityJeverage: That's not all that weird, i know some people who only listen to musicals because they go all the time. This can happen with your termed "regular" songs as well, if you hear them during something that associates them with that memory.
so maybe you should post an article when you have information to share instead of just posting an article to let people know to look for another article in the morning.
