Found an image while in the files of beamng while editing a map, its an image of East Coast USA but instead of just the normal town, it has a small community near the one bridge, its very interesting. I only really use the forums to download mods, so ive never seen anything on this, i apologize if its been discussed before It looks like a more "rural" landscape and as someone who lives in Maryland (i know the area is based off maine) it looks very east coast-ish, around where i live i see fields everywhere and honestly like the layout of this image. Not to mention it looks like there is additional roads and other things you can see, theres alot to name. I feel this looks like a way more realistic and better map of what we have now, This image is from 2013, cant remember the exact date, I played back then but not enough to remember if this map was ever a thing however i do know east coast was updated. If anyone knows anything id love to hear it, id love to see someone edit eastcoast to look like this, would be awesome, i know making a map is hard im not one of those guys asking for someone to make one acting like its easy, its not, but it would be pretty cool.
It appears that this image is a layout sketch done by the environment artist before the map was originally made, similar ones have also been shown during the development of WCUSA and Italy.
03/07/2013 is just a buggy date, every file in the zips have the exact same date. So no, East Coast wasn't in the game at this date, it was released in 0.3.6 at the beginning of 2015.
