When playing the game there is often a lack of difference in the passengers. I would find it much more interesting if the were other types of passengers. I will list a few: Children Different faiths/ethnicities - e.g. a Muslim woman wearing a Hijab. Different clothes Passengers with luggage Animals Passengers with a disability - this could link with a guard mode, making a guard have to take out a ramp or help the passenger up onto the train. Passengers that want to sit in a quiet carriage - this would tie in with guard mode again making the guard have to ask other passengers to be quiet. I hope you like my ideas.
