As for how accurate it is, well I dont know. I was limited by the world engine. Kind of like the old wolfenstein games, you know huge block walls, 90
degree corners etc.
Block size is limited, so when a building should be smaller / larger, I may not be able to get it just how I want it.
I used a few maps and sattellite images. The problem is that stuff changes over time so if you look closely at various images, there are slight
changes that can throw off your entire plan.
I did the best I could with the materials at hand. It would be different if it was like a Grand Theft Auto San Andreas engine
Although they have an area-51 type place in the game. Fun to break into !
. Exactly how accurate is it?
