Don't worry, I'm still writing the next part of my recent series. I haven't forgotten! This is just something I thought about on my way to work this morning...
The following is a ruleset for a light RPG you can play in any amount of time, even less than 30 minutes. Character generation takes 10 seconds, and combat (if you even have any) takes a single dice-pool per 'side'. It can be used for any setting, ever.
Each player chooses 3 things their character is good at. This could be anything, from Strength, to Running, to Talking People to Sleep.
Each player ranks these traits from +1, +2, and +3. You have to use each, and you can only use each once.
To make a test, a player rolls a d6. If they are testing an action against something that they have a trait in, they roll that many more dice and add all the results together.
The GM sets the Difficulty of an action (or in the case of a contested action, the other party rolls and compares the highest). Difficulty 4 is the base-line.
If a player rolls equal to or above the Difficulty, then they succeed. If they get equal to or more than twice the Difficulty, they have performed a Critical Success, and they can describe the extra awesome things they've done.
Combat is fought by both sides adding up all their dice and rolling it as a single dice-pool. The side with the highest total wins, and the other side loses. It is up to the GM and the players to decide what this means.
Weapons and armour, and other gear add more dice, or have cool effects determined in the moment.
Rules of Thumb: Don't be a dick. Play to have fun with everyone. Trust each other. Do these things and the system will work.
