Also, I wasn't entirely sure how many people would be able to guess e.g. Half Life: Deathmatch compared to Half Life: Episode One. Originally, all of the entries would be triggered separately -- but I decided some more obscure offshoots would be hard to guess. For the sake of listing Valve games, I kept the offshoots in the quiz.
