Like Urdnot said, there's too many effects Plus there's so much gold bonuses that stack together that it's kinda ridiculous how much gold would be made by this civ. Then there's also the fact that automatic construction of gold buildings is already done by JFD's Lincoln. Claiming all workable plains, buffalo, and horse tiles immediately from settling is way too much, theoretically you could claim every single tile in the workable radius in your cities. tbh, it's strange you'd make them ineffective outside of war when you'd give them a buff against barbarians. You might as well just leave them with the generic great general buff of +15% combat strength overall to nearby units. The 1 extra movement and bonuses from pillaging are ok though. You'll need to rename the unit otherwise it'll be "Comanche Comanche Raider" in-game The 6 movement overall, again, is a bit much especially considering the Keshik, the fastest and most powerful mounted unit in the game, has a base movement of 5. The ability with being stationed on horses isn't that practical, horses are already fairly common unless you have terrible luck and you already get double quantity of horses with the proposed UA anyways. Using plains as roads is overpowered, that's way too much mobility right from the beginning of the game, especially combined with the +1 movement melee units and civilian units get during wars. A settler could theoretically travel 6 tiles, and I don't know about you, but I'm pretty sure it'd be annoying to have a city spot sniped repeatedly by the AI, especially on higher difficulties like deity, because their settlers can travel so far in such little time. This seems too similar to the Sami's unique scout and its herding ability. The AI would also have trouble settling cities because they'll be confused as to how to settle a city with a unit that has combat strength. Again, you'll need to change the name or it'd appear as "Shoshone Shoshone encampment" in-game . This UI, however seems interesting, but the extra culture from adjacent terrain isn't necessary, the culture bonus from adjacent mountains would be enough. I'm not 100% familiar with the Shoshone, so I'm not sure about their link to the mountains, so I can't comment on that.
