Story and voice acting.

Some of the references to the original Might and Magic universe in the campaigns.

Sorry for the off-topic, but is there a complete list of references to the old games somewhere? Not just in the campaigns, but in general. I'm just curious if I've noticed everything I've encountered. For example, in the weapons of the Dynasty, there are so many references - Iron Quill, Alliance of Angels, Soul Eater, Sword of Wiselbon, Flaming Tongue of the Dragon, Staff of Sandro, Sword of the Griffin.
