Sorry to revive an old thread. But as far as I know, .conan. works in any time period. There does seem to be the drawback that you are superweak if you use .conan. in any time period except the original. So weak in fact that I have only once won a battle, with severe losses, so I gave up afterwards. You can't avoid this by autoresolving either >.<;

If you are bored and looking for a bit of a challenge, try playing a r&r game where you keep each rebel faction seperate from the others. This takes some paper/pencil/calculation work to figure out income percentages, but it can get mad challenging and thus, fun.
