Dungeon Siege is a fantasy action role-playing game franchise originally created by Gas Powered Games. The series includes mainline entries Dungeon Siege, Dungeon Siege II, and Dungeon Siege III, as well as the spin-off Dungeon Siege: Throne of Agony. The games are known for their seamless, loading-screen-free world design and tactical party-based combat.
The franchise's publication history includes official strategy guides such as
Dungeon Siege [Sybex] (1993) and
Dungeon Siege II [Sybex] (2005), which helped players navigate the complex quest lines and character builds. Chris Taylor designed the initial universe, which expanded significantly over the decade. The handheld market was targeted with the release of
Dungeon Siege: Throne of Agony (2007) for the PlayStation Portable, developed by Supermassive Games.
Transitioning ownership to Square Enix led to the development of
Dungeon Siege III (2011) by Obsidian Entertainment, which introduced a more focused, cooperative multiplayer experience. This release was accompanied by various editions and promotional materials, including
Dungeon Siege III [Prima] (1990),
Dungeon Siege III [Bonus Content] (2011), and the
Dungeon Siege III [Nordic Edition] (2011). These releases shifted the gameplay toward an action-RPG style suitable for consoles, moving away from the PC-centric controls of the earlier titles. The series also spawned a film trilogy directed by Uwe Boll, reflecting its broader transmedia footprint during the 2000s.
