Donjon
Donjon is more of a STORYTELLING game than a GRIND SLASH COLLECT +X ITEMS game.
You pick your own skills (say, you decide that your character has Necromancy, Running Fast and ELVEN EYES as skills). Then you decide that, "Hey, I want to use my ELVEN EYES to see what's over that next hill!" then depending on how many successes you get, you get to describe more or less. A weak success and you could go: "My elven eyes see an orcish encampment!" and a good success could be: "My elven eyes see an orcish encampment! They have many siege engines ready for war, and the chieftain's tent stands out, heavily guarded, in the middle of the camp!"
