My Review of the Empires rule system was less than stellar. However I believe in giving credit where credit is due.
The Campaign system is well thought out and easy to use. It makes playing a continuous campaign easy and enjoyable. I heartily recommend this product for players wanting to run a campaign using ANY ruleset. It is a job well done. The fact that it is free amazes me even more. Pick this up you won't regret it and pick up the core Empires Rules as well. With some tweaking on your part they are a great design idea.
