I tend to agree with Gunner and sandman.
As I've said to those who are overly critical of HWN in the past, good luck finding another 3D Napoleonic game/sim that so accurately simulates the movements, tactics, formations, and strategies of Napoleonic era warfare. Sure, if you just want cool explosions and accurately modeled uniforms, Total War will do. But nothing about the game engine of Total War, even in some of the extensive mods out there, accurately models Napoleonic tactics or sheer numbers of regiments committed to battle, like HWLG or HWN. There is not another game in existence that so accurately takes into account formations, like line of march, line of fire, column of division, or column of platoon, like HW. No other game that takes into account corps level formations, like double line or refusing a flank. No other game that takes into account multiple rounds of unit routing before leaving the field, or the intricacies of morale loss/gain, or capture. If you're committed to these elements of historical realism, and you want a complete editor, and you want realistic numbers of soldiers on the field, and you want a 3D game, then I'm not sure where else a person could turn, frankly.
Hope you find what you're looking for, Vags.
