One of the things that I love about this game is the feeling of time passing by. The buildings change, the roads are updated, even the pedestrians wear different clothing. One thing lacking though, is the small selection of personal vehicles. It skips the early horseless carriages, and goes directly to mid 1930s cars. This isn't too bad, but once you get into the 1940s and 1950s, those same 1930s cars are still on the road, not replaced by newer models until the Trabant shows up around 1960, a bit immersion killing, as cars really started to take over during 1946-1960.
Could someone add a few vehicles to flesh out the historic feel of the game? I would do it, but haven't a clue how to 3d model.
