I have tried some of the Perfect Captains rules before and enjoyed. In fact, I seem to recall interacting with them what seems a lifetime ago. I thought I would give a shout out to them however here, especially as they have a number of different types of rules for different periods. I can recommend getting into them, most work well and those that are a little obtuse become clear after a little reexamination.
I am thinking of using these for my hoplite project, I’ll let you know how that goes.
Do slip out and have a look, the Perfect Captain.
