I've made a one page sheet to track most aspects of your civilization. Based initially on the works of redking and with a nod to neverstop77 it includes all building and unit upgrades as well as hand sizes and various bonuses that affect cities, trade and production with checkboxes to tick when various things are unlocked. Designed to be used as a sort of character sheet for your civilization.

Version 3 of the sheet. This one is smaller (although you will still need to fit-to-page when you print. It also corrected the spelling of 'fundamentalism' throughout and corrected the starting stacking limit to 2.
