A Look Back At (or "ALBA") is a series put out by Achievement Hunter. Two people, usually Fragger and Ray will describe a game, its story, its mechanics and its achievements in the style of This Is. Unlike This Is, however, A Look Back At focuses exclusively on games that are at least two years old (This Is focuses on new releases). Also, A Look Back At focuses exclusively on Xbox 360 titles (with the exception of "A Look Back At: Pong", which they did as a joke).
If a prominent sequel is released, that week's ALBA will typically be for the original game/games (For example, A Look Back At: The Darkness was released the same week as The Darkness 2) The show has been suceeded by Retro Active.
