What size of army would you say,
would make a good three to four hour game
On my experience we played 2 24 point games so maybe 36 or even 48 points ?. Also the scenario and conditions would alter the time frame?. We found the mechanics are in your head easy and game play and what happens when trying to activate is very important and Alec noted the pin results make the game work. some way of recording who has been activated also would required for larger forces but most have counters in games now to use.
My thoughts only and thank you for comments and views as always
