I knew if I went searching enough I'd find it for the ECW time period.
Thanks to Fanaticus (you can see the link on my side bar) I have found the DBA~RRR amendments that allow you to play the Renaissance, Reformation and Restoration period. Very happy with this.
Well I bought the Field of Glory:Renaissance rules and Wars of Religion companion and having started to read the rules, and examining the lists, I have a lot of figures to paint. The nut cruncher is that I have to produce two armies, with twice the amount of work. Guess I'm getting lazy. However I am happy that I did buy the rules, they are rather nice. I do recommend that you get yours through QBD as the price is a lot more competitive than some of the LGS.
So I'm off to ponder my ECW now in DBA~RRR. Will post pictures when things come to hand.
