On my blog, I've been running though the Battle of Callinicum using different ancient rulesets. The focus is on rules that will give a game in under an hour on a 2'x'2' board. My most recent refight (the sixth) was with Mighty Armies Ancients. I've had these rules for a over a year and am glad to use them at last.
Included in the report is a comparison of MA and MAA, some comments on the way through, and my (positive) verdict of the rules at the end See the link below to directly go to the MAA refight.
