One of my biggest disappointments when I first went through the scenarios in Exp#1 (besides the absence of Thermopylae and Chaeronea) was seeing Spartan armies with the suggestion of using Persian blocks... I could understand it for Successors battles, after all they were being "Easternized", but Sparta???
You will say "well, there are just a few battles", if I remember well Leuctra and Mantinea, but the problem became bigger for me as most of the 15 scenarios I have designed (Greek Tragedy, Hellenica and Sacred Band) involve Spartans. Or at least other Greeks.
I began using the gray Roman army for those scenarios, better looking than the Persian but I was not fully satisfied... And then I found a cheap solution. I'm using glass stones as generic Victory Banners, and small plastic shields as Special Unit markers. This leaves me with 56 Black blocks (yes, I have all expansions)!!!
I've used them to build a 7th "Black Army": Sparta. The "only" thing I had to do was work on new, Spartan-like labels for these blocks (GET IT HERE).
The art for HI, MI and Aux is new, I drew it big by hand, scanned, colored, reduced and pasted it on the empty label background found in the Reference Cards. So the results are better quality than the previous file I did (I've completed the page with extra labels). For the few Cavalry and LI needed, I've painted spare blocks in Black and used existing (slightly modified) art.
And thanks to Alessandro I will be able to play all these "Spartan" scenarios online!

I hope you will all enjoy them at least half as much as I enjoyed making them.
