5 cities set from large to smaller in size that fit on one city street that spands out that is large but will only hold one city at a time. you can combined the cities together after you place the each on a street map for each one. Then set the scenes how large you want. each of the 5 cities are different. each city is flat and will sit on any flat terrain in your game as long as you resize to fit. I have tested them in UE4 you need to resize each city and the street to fit player size at 5550 for x,y,z and rotate it to 90 on x side. then it will be flat. make sure to center it up with street map obj and center your city to the same position in your game editor.
