Nice first campaign, and a new faction that boosts value to this expansion.
The first campaign, Armageddon's Blade, is the most exciting and satisfying campaign to play since it involves the assembly of a powerful artifact through the scenarios and you get to unleash its powers at the last mission. It makes re-playing an old game rewarding and refreshing as well. The rest of the campaigns are interesting as well, including a wizard (titans) faction that doesn't have mobile enemies, just powerful dragons that block your way. Own time, own target. Nice.
The graphics are the same, even the music doesn't change at all, perhaps a new theme for the elementals, but it should suffice with so much new content to allow Heroes III to be fun again.
