I don't know how I feel about using terms for it that have little involvement with the game itself.

Something symbolic like, pertaining to rebirth would be a good idea imo. I like Zells choices. Legacy and Phoenix. Legacy, for those who stuck through the hardships of the game, getting to tell all those about how the game used to be. Phoenix being the rebirth of a game that rises from the ashes.

Might be a little corny, but I'm really partial to combining the two for the "Phoenix Legacy Engine" or PLE for short. just my two cents anyway. >.>
