Frank, Im assuming your refering to the WSS here. On that premise and having never played any, I'd be open to trying any of them. BLB (Beneath the Lily Banners) for those who like myself are still learning of the WSS, Pike and Shote or any of the other systems that many gamers have mentioned here.
On that note, out of curiousity, some time back, I started my own thread "Whats your favorite rules?" on this same Category: Horse & Musket: War of the Spanish Succession.
As I was / am eager to learn more of gaming this war and period. I must admit here, I have been thinking even earlier periods might be fun, i.e. ECW, as I find massed ranks of pikes both intimidating and they look great on the game table.
Sadly, IMO, their 'stuck' here on the traditional "Nap" wars when it comes to the late 17 or early 1800's.
At our local hobby shop we have a near "devout" group of "Johnny Reb" players, like many fellow gamers, meet on a set routine, i.e. every 1st or 2nd etc wkend of the month to play. I admire that kind of consistency.
Your own 28mm "Risk" game, I love that idea. It reminds me of a 'home made" game I saw several years ago. A fellow had used 25mm's and had done his own version of a 'Memoirs'44' style game, but of the ACW period. The units were '3' figures each, one could be removed to account for causalties, then put back on the board when 'that' unit was reduced to a strength of only '1'. He did the same for Cav and Art. It was really a visual treat.
OH, and just FYI everyone, the 'game board', if I remember was either lite wt. indoor / outdoor carpeting or very heavy cloth that he had drawn a 3 - 4" hex grid upon.
Now.. as for that "little Corsican..."
I'd say we take him down a peg, but God already beat me to that. LOL
