Five by Five (3rd Ed.)

From the web site introduction:

Five by Five is a "choose your trait" style RPG that makes unique use of six-sided dice to create an easy to learn and easy to play universal game system. The game is flexible enough to satisfy a variety of settings and easy enough to pick up and play right away.

The core of the system is the 5×5 die roll. Players roll two dice (reading a 6 as "0") and multiply the results. This gives an average unskilled person around a 30% chance of success and each rank of skill improves this chance by 5½ percent.

The game includes sample adventures for both a fantasy setting and a superhero game, example characters and a character sheet.
