Parídíne

From the quick play introduction:

The narrator will setup a quest, mission or bounty, and give you the background story of what needs to be done by your party. Some Narrators may just throw you in a dungeon and slay random monsters.

From the Players Tome introduction:

Parídíne is a "free to play" fantasy combat game that was designed to keep combat and dungeon exploration exciting, fun and competitive. The idea and concept was to take as much control away from the "Dungeon Master" as possible. This doesn't mean the game doesn't require some kind of a narrator; It just means that the game is automated enough to draw out its own story-line using its own mechanics. The game is intended for 3-4 players not including the Narrator.

User summary:

Parídíne focuses primarily on tactical combat and mechanical methods for creating situations and adventures. Roleplaying elements are pervasive but not prominent.
