MYNT: Maybe, Yes, No, Twist

From the introduction:

The MYNT system is designed to focus on storytelling through roleplaying while remaining rules-lite. It can work with any setting. Combat is possible but it is not the focus of this system. It was designed to get players doing more than swinging swords or shooting blasters with the aim of beating a particular number in order to succeed. Action and adventure occur through twists and not continued success on the part of the hero.

Think Han Solo, Indiana Jones or Jack Sparrow having to talk, trick or fight their way out of a situation and being smart about it, but things never quite going as they planned. This system is designed for just such events.
