BioWare's iconic role-playing game Knights of the Old Republic will be half-price, £3.50, on Steam this weekend.

It's part of a weekend-long Steam Star Wars deal timed to coincide with the Blu-ray release of the Star Wars Saga.

Other discounted Star Wars games on Steam include Battlefront II, Republic Commando and Empire at War.

Knights of the Old Republic reinvigorated the Star Wars licence for gamers. It's set thousands of years before the Star Wars films. You are a mysterious stranger with no memory of your past. You escape an attack on your rescuer's ship, and your subsequent mission to rescue a Jedi marks the beginning of an epic tale.

Eurogamer called Knights of the Old Republic as "the best Star Wars game since X-Wing and/or Tie Fighter, if not ever". Kieron Gillen's Knights of the Old Republic review for Eurogamer awarded a delicious 9/10.

The success of Knights of the Old Republic lead to a sequel (developed by Obsidian) and to BioWare's biggest ever project, MMO Star Wars: The Old Republic. The success of KOTOR also helped bring about the Mass Effect series of games, which share many similarities.
