I can see the potential on adding in passenger behavior, such as like what you have for example bAnderson, passengers on a budget. I do charge a bit for the snacks, but the highest I ever go for the snacks in my IFE is $10.
I'm not sure how the AE developers would be able on creating a system where there are different passenger preferences, but I can see something like that being done to make the game a bit more challenging and hopefully more controlled to where you don't see people with 2,000 planes by the end of the 4th year in one world.
