We are really complaining about the lack of women on the main cast of a WESTERN game?
Except for that movie with Sharon Stone I can't remember other story about that time that had a woman as protagonist
I mostly agree with you, but the new True Grit is a pretty good western with a female protagonist.
But, to reiterate my point, Bonnie McFarland was a main character of a Western game and she didn't appear on the original poster or imagery for RDR, and she was a great, important character in the game. So, it's too early to criticize Rockstar either way, either with "I can't believe there's no female character!"
Also, R* specifically mentions Online in the byline for this... Which may suggest that creating your own character is a significant part of the game, which allows someone to create any character they want. I sort of hope that Online is not a main focus on the game because I'm turned off to GTA Online, but who knows.
