Too much Mexico, not enough indians (not at all, actually)...  
Call of Juarez 2 almost pulled it off, but it ended up feeling kinda meh, but i applaud their amazing attempt. RDR should've had some Running Water or Buffalo Diarrhea instead of Reyes and Louisa..
 
WTF amirite ?

It's 1911, isn't it a bit late for Native Americans?

Have you unlocked West Elizabeth yet?

I don't know my American history, but the game takes place in 1910 or something. At that point I'm pretty sure the whole "Cowboys and Indians" thing was dying.
 
Correct me if I'm wrong.

Yeah, the time period doesn't lend itself to having a bunch of native americans running around. You do eventually see some near the end of the game but only on missions.

That's what I'd say too. It almost makes me wonder if they set the game so late so they wouldn't have to deal with the issue. "

They are all DEAD! It gets addressed during the end of the game

You mean indians? 
 
What is this, PC World?

Dutchs gang has aplenty of them, I thought.

Blame America.

I agree about the too much Mexico. I honestly thought that was the worst part of the game. I was glad to leave it. Never went back.

They were mostly moved to reservations by then, I think.

I think the 1911 setting of the game showed the Native American's as a dying breed as they were pushed further away. Having them wear predominantly settler style clothes and wielding guns were particularly telling of their culture in disarray and the changing landscape that fit in with the game's motif. 

SPOILER ALERT !!! (can't make the spoiler box working...) 

 At the end of the game, the junkie author McDougal sets up a meeting with some native americans. They turn out to be not so friendly, and he tells them that it could end as a "disaster" if they don't lay down their guns. The natives answer: "Oh, I think we already experienced disaster". 

 
SPOILER END  

 So yearh, I think the time of the natives were over at the time of the game..

It is 1911, I am pretty sure we "got" all of them. 
 
But there are some in the later part of the game, some.

I agree about way too much Mexico.

" @Chabbs0:  well im colorblind. and cant see anything :D "

" @MysteriousBob:  mexicans are NOT Indians my friend. "

Yeah there aren't many Native Americans in the game because the Europeans have already killed off most of the Buffalo, and the Native Americans by the year 1910.  If this game is historically accurate, which it seems to be.
