Hi gustav,
I've played a lot of wargames rules over the years, and quite a few Napoeonic ones and C&G is right up there with the best of them.
I wargame Napoleonics in 18mm specifically to a allow the big game to be played, which I think is what the period is all about. This game was as much a test about the ability of the rules to manage that as it was about developing the scenario, and the beauty of the system is that you get all the detail around weather and fatigue without having to think about it. The players just concentrate on commanding and moving their troops.
As you might guess, I like them.
