Here's my plan for a new concept map of mine.
And here's the names if you can't read them:Spoiler
It will be based somewhat off of The Crew. This will be in island map, but the areas with diagonal white-and-gray stripes indicate landmasses that are off-limits.
Dude, I can help you with New Hampshire towns and cities seeing as it's my home state.
Well, other than Bullworth, I won't be expecting to put in much of New Yorkshire...and this map will have the idea that it'll take one real-world hour to drive from Los Santos to Vice City.
I'll start with the cities when I get time to work on them.
UPDATE: I have begun work on the GTA America concept map (title is still a placeholder)-using GTA V's Los Santos as the starting point, I've already begun adding a second urban area north of LS based off of the San Fernando Valley in Los Angeles-right now, I'm adding a road that marks the southern end of that area that's based on Ventura Boulevard in the actual SFV.
Current plans call for the same map file to eventually include San Fierro and Cascade City in version one.
