Angel Studios previously used the game engine Angel Real Time Simulation (ARTS) for Major League Baseball Featuring Ken Griffey Jr. (1998) and Midtown Madness (1999). The following year, Angel Studios developed Midtown Madness 2 (2000), the first title to use the new Angel Game Engine (AGE). In 2002, Angel Studios was sold to Take-Two Interactive, moved under Rockstar Games, and rebranded Rockstar San Diego. This sale also included AGE, later renamed the Rockstar Advanced Game Engine (RAGE).
