The original Knights of the Old Republic game has been on Steam for some time now, but finally the sequel - Star Wars: Knights of the Old Republic II - The Sith Lords - has made it to Valve"s service. Originally released for Windows in February of 2005, the game was well received like its predecessor and is known as one of the best Star Wars video games available.
Buying this game will set you back $10, just like the first game; however at this stage its only available for Windows with a Mac port currently unavailable. Thanks to the age of this game, most PCs should be capable of playing it thanks to low system requirements. If you want to purchase the game, head to the source link below.
