The game concerns history. The history of Christians is important to a game about history. Sorry.
"If you want to play computer games, you'd might as well put up with it, because that's the way the cookie crumbles."
Not necessarily. One of my all- time favorite computer games, 'Freedom Force,' (It's a strategic rpg where you control a team of superhoes) doesn't stoop to being really politically correct, other than the fact that one of the heroes in it is black and another is Latin- American. In fact, one of the major supervillains in the game, Nuclear Winter, is a Russian Communist who wants to hold the city hostage with an atomic bomb(The game takes place in the 60s, when the Red Scare was sweeping America, so it kind of parodies that). There's also a rather funny scene in which one of Nuclear Winter's henchmen tries to shoot the heroes with a freezing gun, but it malfunctions and blows up in the henchman's face, knocking him out, to which Minuteman (The game's ultra- patriotic main hero) replies, "You should have bought American, friend." In fact, at a Christian site that reviews games, the only minor complaints they had with 'Freedom Force' are that one of the female heroes, Eve, is immodestly dressed, and one of the villains is a Greek god.
So, not all games have to be PC.
