Interesting thread on TMP here, regarding a recent 10mm re-fight of Blenheim during the WSS. It has links to a very nice picture album of the game as well as links to the D&P site for the free downloadable rules module, "Le Roi Soliel" and a set of army lists for Blenheim. Well worth a look!
And now, confession time. I have never made a secret of the fact that I am a devoted fan of George Gush's Renaissance rules, both 1st and 2nd editions. However, as the rules are a bit "long in the tooth", I have been exploring mod's to the rules and/or other rules sets for my favorite period. When I first became aware of "Basic Impetus" and "Impetus", and their free expansion modules, I will admit that I didn't explore them in detail because they are of the "Grand Tactical" nature. It's strictly a personal preference, but I usually don't care for the "one stand equals one regiment, brigade, division, etc." sort of rules. My preference has always been the more "intimate" 1:10, 1:20 or similar rulesets. Years ago I participated in some of the playtesting for several sets of published Grand Tactical rules for the SYW and the Napoleonic written by friends of mine and just never got my head wrapped totally around them.
However, now that I've looked at the pic's of the Blenheim game, and downloaded the rules and lists, I may be changing my mind, at least a bit. I was impressed enough with them to also download the "Basic Baroque" expansion mod for the 80 Years War through the Late 17th Century (and including the GNW), which also look very nice. You can see them for yourself and download them here. While I may always prefer the Gush-style rules for a battle like the 2nd Dunes, I can really see using these "Impetus" modules for the larger battles like Seneffe, Enzheim, or the major battles of the War of the League of Augsberg. The scale really does allow you to perform the grand, sweeping movements that featured prominently in many of these battles, and they appear to be very well written for a fun game.
If any of you have direct experience using either of these "Impetus" modules, I would appreciate hearing your comments and input.
