History is good bad and ugly, if we erase what we don't like, we're not being honest about it, and in some minds, are trying to deny some parts happened. we can put things in their correct context, without denying they existed. this particular game works in a set time period, and if it actually reflected a lot of what really went down, most of the cowboys would look, well.....different.
you want the dime store novel romance or the real deal? might lose a lot of fantasy lovers.
