I'm going to second the other commenter in my enthusiasm for GURPS, but for the opposite reason.

Gurps has the problem of being a universal role-playing system, like Fate, which means session zero includes a long sit-down with your DM about what precisely we will be doing in this game and what mechanics we will be using to create the desired experience. You then fill out the appropriate forms in triplicate to create your character. Usually, your DM makes a template for you to use like a shopping list, but the rulebook assumes you are digging through the first 300-page volume selecting your abilities and skills over the course of a day.

Then, once you start playing, you never have to look at the rulebook again. All the rules you will be using were written (by you) on your character sheet. You roll the dice, see if you managed to roll under your target numbers, and then either succeed or fail. The DM barely has to adjudicate anything.
