I know, this isn't vital to the game functioning, but I'd reckon that being able to chage your player model's sex, hair color, facial features, etc. would be an immersion booster of epic proportions. It would aid in immersion and/or fun both in singleplayer and in multiplayer, especially when playing with friends. Potentially, templates could even be made and shared with other players. EDIT: This is also a suggestion for regular Train Sim (=/= TSW).
