Back when we were limited to small maps I thought about building a map based on Trinity sort of like someone built SmPizza loosely based on the original Pizza.
I never got further than the rough idea below. Darker is higher, light green is approximately sea level. Gray are canyons. Red seperates countries. GV bases are red and connected by spawns and airfields are in black. Note the mountain ranges run through the middle of each country. Also note the high airfields in the back to let bombers get to alt.
Maybe someone who knows how to make maps could do this one.
