I was playing with this, and a few people like it. So I am banging it here so I can link to it from things other than Twatter/Instagram. People have since asked for Fallout 3 and 4 maps.

The geographic size of the map bares little relation to the size of the map in gameplay. This is just to demonstrate the areas covered in the games. But those that are interested (thanks to DudeOverdosed on Reddit) to walk from corner to corner of the maps it takes:

• Fallout 4 – 56 Mins
• Fallout New Vegas – 1Hr 9Mins
• Fallout 3 – 1Hr 11Mins

Here is a YouTube walkthrough of it (sped up).

Maps of Fallout 1, Fallout 2, and Fallout: New Vegas overlapped.

If you stretch Fallout 2 to the east the topography lines up slightly better for the mountain range. Vault 13 and 15, along with Shady Sands/NCR do not line up, so have been moved between games.

Fallout 3:

I like the jaunty angle! I have used the Potomac river as the reference point. The river doesn’t follow absolutely correctly, but it has dried due to a nuclear war.

The White House is in the correct place too. So I am happy with that map.

Fallout: New Vegas

This map lines up very well, the primary reference point is the Colorado river and the I15. These line up almost perfectly.

Fallout 4:

As yet I have not played the game, or done any reading on the matter. As a result, I don’t know the lore, or any reasoning behind it.

But… The maps do not align very well. I can align Manahat, and the rivers. The rest are way off. I have used the junction of the Charles and Mystic River as my primary reference point.

<Edit: Apparently the map was scaled to allow for the settlement system work>

To give you an idea of scale, this is around 8 squares around the Cathedral in Fallout 1, or purely the sections immediately surrounding New Vegas City.

Here is the map with transparency, so you can see the coastline.

All Maps combined

So, slight disclaimer… Zooming so far out removes any details I can align too. But by eye, this is ROUGHLY how they compare.

I am surprised how large New Vegas/Mojave desert geographical coverage are compared to 3 and 4.
