Game mechanics that allow you to play the battles you love to read about: Big battles, multi-corps battles, where reserves and planning matter.
Manage your own sector of the battlefield but care what is happening in the others.
Don't be pigeon-holed into small parts of large battles when you can run the whole shebang, in real-time, at any ground scale you like.
Lead the attack upon the Pratzen as Soult, while in the same game Davout stubbornly defends the right flank against the Austrians.
