Hello Mr. Smith,
as Chris said, we designed the rules for 28 mm but you can easily adopt the rules in any other scale, although I recommend 28 mm.
Concerning the basic systhem I can say that we use d10 and d6. We have unit sizes from 5 to 10 for regular or up to 16 for "irregulars"
We have a troop quality that varies from Raw to Elite.
Our initiative systhem is pretty new I guess and doesnt work the static I go you go way. It is easy, fast and exciting.
We have Leaders and Heroes and we have a skill systhem, rules for Vehicles and heavy weaponry.
Hope that helped a little.
Cheers
Björn
