Last month I played in a fun Colonial Sudan campaign game. It was just a small engagement, British vs. Dervishes. I was on the British side trying to take a town, with some help of a gunboat. Dan (who is running the campaign) played the Dervishes. The battle rules for the campaign are The Sword and the Flame. Everyone knows these rules so I won't go into description about them. What I will say is I got into historical miniature wargaming 29 years ago because of these rules. I think I got burnt out on them awhile back, but this campaign is fun and the rules are not that bad. The subtle changes/additions to the rules have improved things. Also, Dan always puts on fun games.
