-edit- Since all the horses are supposedly extinct, rideable Brahmin anyone? http://www.youtube.com/watch?v=5NUXYdI3H6E
Nooooooooooooooooooooooooooooooo, they are not!!!!! Maybe they are just extinct in the parts where Fallout has taken place so far? Or just rare?
I think NCR troopers fit perfectly on horses, they are clearly inspired by british world war one troops, and in that war they rode alot of horses.
And I love that war, not in how many people died and cities got destroyed, but how there was new technology mixed with old tactics.
Machine guns and mustard gas, trench warfare and infantry charges (and cavalry charges).
Also brahim are slow i can't see anyone riding a brahmin across the wasteland
Have you ever seen a brahmin run? They can be fast, but no animal can run fast all the time.
If the caravans would have pack horses, they would probably be just as slow.
In Fallout 1 and 2, the brahmin pulled carts (made out of half a car) though.
