So like a week ago I was really bored and since I'm a massive fan of the Fallout games (1,2,3, and NV), I decided to go into Google Earth and mark as many of the real world locations of Fallout locations. Then after that was done I added some more of Fallout location that don't exist, getting them as close as I could to a logical and accurate location. I started with New Vegas as it has a LOT of real life locations there. I also outlined what I guessed what was the playable world for the 4 main Fallout games, I think I'm really close (give or take a few miles in any direction). I marked part of I-15, but not all of it. I'll probably map out more roads in the future. I intend to use what I created as a reference when I'm making mods for Fallout New Vegas. If you're working on a mod's story, it's good to know exactly where everything is.
It's an ongoing project, though I got most of the important stuff done.
Here's the .kmz. Enjoy. If anyone notices a flaw and thinks they know of a better location for a fiction place, let me know and I might change it (might being that I might not agree).
