One thing I would like to see in this game is an Indian character.
Of course there would have to be special weapons only an Indian could buy. Tomahawk, spear, bow and arrow, perhaps in place of pistols. (Anyone ever hear of an Indian using pistols? They did use rifles when they could get their hands on them.)
I have no idea if this is even feasible. But I love the idea of bringing Captain Jack or Geronimo back to life and taking a few scalps!
