Ruff, ruff!
This quote comes from one of the only, if not the only (aside from Half-Life 2's Alyx Vance), video game companion that never becomes annoying or troublesome to gamers. One of the most recurring problems in any video game is that of trying to create a companion in a video game that can tag along with a player character's exploits throughout a game in a fashion that is not only realistic but, more to the point, doesn't require constant babysitting to avoid the common video game companion pitfalls of getting stuck, going the wrong way, or committing suicide in one of any number of possible ways depending on the hazards that fill a game world. It's an understandably difficult game mechanic to have in that, especially in an intimate single-player game experience, to have an AI intelligent enough to act predictably "human" in the same way that the person controlling the main character would act.
Ruff, ruff!
This quote is arguably the most memorable thing that players will experience in all of Lionhead's recently-released Fable 2. It doesn't come from farting to impress women to the point of marrying you. It doesn't come from the manual or various cinematics. It certainly doesn't come from the wooden and awkwardly-presented narrative cutscenes. No, the above quote comes from -- and I'm sure this is a surprise -- the only dog known to the world of Fable 2: the player's dog that can change names as often as it changes collars (no, really). The little furry fella attaches himself to the player's character from an early point in the game and, from then on out, is by his side throughout a majority of the rest of the game. The dog is not the interface but, instead, a helper to the main character; he will point out treasure chests, dig spots, and he will help in combat from time-to-time.
