The folks at Mana Pool have gotten around to reviewing Star Wars: Knights of the Old Republic, awarding BioWare's first stab at a console RPG with a much-deserved 8.8/10. Their conclusion:
If you have not played Knights of the Old Republic yet you really owe it to yourself to grab a copy and give it a go. You don't need to be a Star Wars fan to enjoy this game, the story stands alone from the movies and other material and the background is explained pretty well throughout the game. You can play this game without ANY prior knowledge of Star Wars and still have a great time. For those people who do like Star Wars; this is probably one of the greatest Star Wars games ever made.
You can purchase this game for £6.99 on Steam or under a tenner on Amazon. Depending on how thoroughly you go through an RPG, you can expect a playthrough to last 45-60 hours. You will enjoy this game at least twice (Light side and Dark side) so you should get roughly 100 hours of great gameplay out of your money. If that isn't value for money, I don't know what is go play it already!
