The chit draw activation for units and certain events creates a wonderful tension in this elegant game. The CRT is straightforward with terrain, principally cities and towns, nullifying some of the results. A one against city will produce a null result regardless of the odds, while a six is normally a win (units take losses and/or retreat). With infantry having a movement allowance of 3 and it costing one to enter or leave an enemy ZoC, once committed it is hard to change the axis of attack.
This game would play really well solitaire, pity I couldn't find a Vassal module for it.
