Sendak actually hit on a rather important part here.
I've adopted, so to speak, a method of one of my fellow gamers. My buddies and I are long-time gamers, but all recovering GW gamers as well. We found it very difficult to get everyone interested in a certain period or game or system. We now have a "host your game" philosophy whereby a single gamer who takes interest in a period will host the entire game. The others simply partake in the game...and buy miniatures if they become thoroughly interested.
For example, when I play Old West I normally run Shoot N' Skedaddle, and I bring the entire table and all of the miniatures required. A couple of my buddies have a dozen or so cowboys painted up but they don't buy full towns, build tables or invest heavily in any rules. I have some buddies who host and run VSF games, some who love to run WW2 games etc. Because of this system (which works quite well) it is always easier to run skirmish scaled games, because I don't have to paint up two huge forces for games. My 40+ cowboys will cover just about any Old West game I want to run without fuss.
I am anxious to try WW2's new Chain of Command rules - but I'll likely be keeping it to small early (1939) platoon level actions...no interest in massed tank formations, huge waves of infantry, or D-Day beach scenarios!
