Personal fave - Birthright - multiple levels of play. PC role-playing, ruling domains (think Diplomacy meets Risk), massive combat (armies and armies and zombies oh my). Low magic item - high magic impact. Human subraces, each with their own specific advantages and disadvantages.
Dark Sun is my 2nd favorite. Using the revised psionic rules. Psionics and low magic (well actually differently based magic). This setting had a high mortality rate which is why the core rules developed "character trees" to keep players from falling too far behind when their character died.
