The Riddle of Steel (2001)

From the back of the book:

Experience:

• The most realistic combat system in any RPG, requiring thought, strategy and cunning - not just brute strength or a hack-and-slash mentality.
• Limitless use of sorcery and magic - sorcerers create their own spells on the fly with easy-to-use guidelines.
• First-priority on who a character is, not what a character is - characters progress as they further their own beliefs, goals and destinies.
• An immense campaign world, Weyrth, with over 40 distinct nations, races, religions, and cultures.
• Simple yet detailed game mechanics for all levels of gamers, from beginners to hardened veteran.
• Core rules and world guide contained in THIS BOOK! No annoying "Player Guide" and "GM Guide," charging you double the money for the contents of one game!
• Complete player support online including downloads, articles, forums, tips and more!

Blade of the Iron Throne is the spiritual successor game to TRoS, so you might want to check it out.
