RPG based on Might and Magic.

I was thinking, why make an RPG about Enroth "after" the cataclysm? It would be much more interesting to see the events before the cataclysm. And it would be better if the RPG didn't participate in "global" events. For example, it would be cool to chat with Archbald before the war for the inheritance in a relaxed, home-like setting. =) Why reinvent the wheel when everything is already ready? Or is it just a desire to have something "original" and unique?
