I was thinking about pikes peak today, and how it could potentially be included in a future update. So I got playing with google earth, and was comparing the map size of Horizon to real-world places. And the results were a little disheartening...
In this diagram, I've scaled (roughly, but within probably 1 or 2% accuracy) the Horizon map 1:1 with a real location in Colorado, the area between CO Springs and Pikes Peak:
As you can see, the entire
map of Horizon is only slightly larger than Pikes Peak itself (the playable area is probably smaller), and much smaller than even Colorado Springs, which isn't exactly a massive city. I also found that most of Horizon's world would fit pretty comfy on Manhattan Island (about 3 times as wide, but only 2/3 Manhattan's length) I think this explains why Horizon never feels as vast as the name has pretensions of suggesting. You can run clear from one side of the map to the other in about 5 minutes. Hell, the entire map is only about 5 times larger than the space enclosed by the Nurburgring...
Basically, I'm suggesting that Pikes Peak is not going to be possible in Horizon. Not ever.
An amusing aside: Assuming that the proportion of the largest mountain in the game (NE corner of the map) is similar to Pikes Peak, and it's scaled according to the map above, it's summit is probably only slightly higher than 1/4 mile (1400ish feet) in game.
*This is based on the reasonably popularly held belief that Horizon is about 63 square miles, which I think is correct.
**Awaits the flames.
