I played Iain at Napoleon's Triumph last Sunday. Poor Iain wasn't really in the mood for the huge mental gear-shift involved in learning this game. Previous wargaming experience isn't much help, indeed may even be a hindrance.
In fact I destroyed him (his words not mine) after just four turns. As the Allies I managed to succeed with the plan that they failed with historically, smashing the French right wing before they reinforced it.
This is a stunning game, both visually and intellectually. Not yet sure if I *like* it, but I already have a huge respect for it.
