Yeah, Ive tried just about all of those rulesets, and I love that website, have used it many times. The thing I dont like about Napoleon's Battles is that it is more abstract than Carnage & Glory, but the thing I do like about it is that it is better to use for extremely large battles. I prefer battalion level rules, but if youre fighting Waterloo, Napoleon's Battles isnt bad. Also a lot less miniatures you have to paint. The best thing about Carnage & Glory to me, is that it takes care of a lot of the tedium, like calculations and things you will almost certainly forget about such as artillery running out of ammo, how much fatigue a unit has, etc. It also has an outstanding program for unit qualities and leader stats, much more complex than the other rules. It really makes me feel like Im watching an actual battle take place from the era. I cant wait to put on the Battle of the Fletches, we had done it before with another ruleset, but arty had unlimited ammo, etc....cant wait to do it with this ruleset. The computer determines all chances to form square in front of a charge, and whether the cav can stop etc...very cool. The game also runs much more smoothly and I end up less cross-eyed at the end of it.

(I havent tried Shako yet, Ill have to check that out)
