Even as a rough concept, this sounds truly awesome and innovative. I'm very excited to play this game when it comes out!
As far as random events occurring, as was discussed in the demo, I have a couple of suggestions which I hope will be considered, and won't be too ridiculously hard to implement.
First, it would be great if someone would randomly forget things on the train, such as a purse, a cell phone, etc. And if you didn't turn them in to the proper channels, or kept them for yourself, you could lose your job and thus the game, or be penalized in some other way.
I was hoping for something like inclement weather, but as the train runs underground, I don't think this would be realistic, sadly. So, could one of the disasters we have to recover from be power outages?
Finally, it would be, well, cool is not the word, but perhaps realistically cool, if we would have to deal with something like a passenger throwing up on the train. Obviously, this would have to be cleaned up when the train reaches the next station. if not, your ratings would go down, because nobody wants to sit in a barfmobile, lol.
Thanks for the awesome job you're doing, and as I said, I'm definitely looking forward to playing this game!
