Wing Commander IV: The Price of Freedom

The first game set after the end of the Terran-Kilrathi War, Wing Commander IV depicts a galaxy in the midst of a chaotic transition, with human civilians, Kilrathi survivors and former soldiers on both sides attempting to restabilize their lives. The game includes branching conversations in which the players must choose what response their character will give; this may affect the other person's attitude, the morale of the entire crew, the next assignment and even the end.
