Got to play some Napoleonics today down at the shop. After playing several rules systems over the years, I believe I've found the one I like the most, Shako II. Each unit is a battalion or battery and each side can easily run a corp. I find the command and control system works well without bogging down game play. Yes, it has it's problems, but all and all it runs pretty smoothly and concludes in a realistic manner. The best part is we can get a corp level game finish in a few hours. Another thing I like about it is that there is a scenario book that you can buy for the system, and from what I understand, more are in the works.
