Rules rules rules

I've been on a bit of a hunt for good rules for the periods that are exciting me. I want one that are thematic and easy to play so the boys will enjoy them but then I keep coming over all old school. I think I'm going to go with In the grand Manner for Napoleonics with 30mm Spencer Smiths bulked out by perry plastics, although I might dabble in Black Powder. For the late 19th century I think 1866/70 May edge it over BP, and I don't like the idea of the command roundel in Zouave 2 so expect to see those on eBay soon. 

The great clear out continues with the 20mm Napoleonics gone and it likely that the majority of the 28mm WW2 will follow as I've discovered the joys of Rapid Fire in 15mm, and can also use those figures for IaBsm if needed. I think if the Battlefront Cold War rules and figures are any good, then the 28mm Russians could follow
