but the station porters and baggage add more realism to the game 

i don't think its a negative thing to add, its just that you have to be realistic. I would expect that out of a big box studio who has tons of people working on the project. This is an indie game with one person working on it. There are better things that change the experience more than some aesthetic shit like porters. it would waste time and take frames away from us. be realistic.
