Breaking a habit is no easy thing—even when a game designer does their best to give players options.
Take Call of Duty: Black Ops II, for instance. Few things are as seductive to a CoD player as perfecting their kill/death ratio, and little about the game is designed from the ground up to encourage anything other than lone-wolf, kill-focused play. Even if that wasn't true, could you blame the average player? For years, the franchise has primed them to play in a certain way.
