I came across Blackstar a rules light sci-fi space opera style RPG. It uses 2d6 with a target of 9 and likely 2-4 points in abilities and talents. It has a character structure that emphasizes the roles one has in the game world. Diplomat or Mystic Sword master for example.

Give it a look if you are interested in that sort of a thing. I think it is well written and easy to bring to the table
