Imagine Code Geass without "magical eyes", mechs, ideas like "the one who yells louder wins", immortal women and stupid idealism (hi Suzaku). You with me so far? Now, imagine Code Geass where there are dozens of great commanders like Lelouch on both sides, where political intrigues, plots and schemes are far from uncommon. Imagine battles of epic proportions and war on the galactic scale, where winning side is decided only by commanders intelligence, number of troops, their morale and available resources, not superunits like Lancelot. Do this and you've invented LoGH.
