the Sioux are heavily criticized here and at the 2K boards
We have seen with Civ 5 Firaxis wanted to avoid the nomadic and largely non-deserving Sioux
Respectfully, I really think you sell the Sioux short. They're as deserving as any NA group, and certainly more prominent than most. Whoever said they're nothing more than a quintessential Indian to a Hollywood cowboy really needs to do some more research.
If they're not your first pick, no problem. But undeserving? I disagree. I'll leave it at that.
