You've probably seen DYOM projects like "Background of GTA SA". In most cases, they are silent about the episode about the feud between the so-called “sets” and Groove Street. This DYOM project will show how Grove Street fell apart into “sets”.
Seth (English Set) - a separate subgroup in a gang. Each set can have its own colors, signs and gestures. Sets can fight with each other (for example, disagreements between families from Grow Street and other families in GTA San Andreas) or they can coexist peacefully (Ballas sets in the same game).
