I really like their games and have every one, except some additions to Alecta Jacta Est. The one issue that keeps me from playing them constantly is the supply issue. Yes, I get it is ground breaking the way they do it, or some such, but I just cannot get my arms around it. I do everything all the AARs and do everything that people tell you to do and yet, I still find armies that SHOULD be supplied, almost completely out of supply. I've played plenty of wargames in my time and have never had these types of issues and there have been all kinds of supply mechanics.
If they had a simplified supply system that you could check a box to use instead of the complicated one, then I'd be 100% on their games, meaning yes, I have 100%, but I don't play them constantly. As it is, I'm about 75% and 75% doesn't make me play every night.
If there is going to be a grognard system of supply, let us fill up wagons with a button that says "Load Supply" then move it in however many turns it takes and then when we get there, we can do "unload supply". That way I know if my army is going to have suppy or not in a remote area that has depots but for some reason cannot get any supply through.
Regardless, I'll get AACW2, because of them all I like ACW the most and Rise of Prussia second. But Rise of Prussia is the one I really have issues on supply, so I rarely crank it up.
Also, I'll say you can't beat the guys at Ageod for taking care of their customers. They're great at that. Great interaction with them and I respect them all and like to support them.
