I feel a little "out of place" talking about the game so much. I am sure others who test played the game much longer would do a better job explaining things.
I can share with you the premise of the game...
After the eviction into darkness, Lucifer and his devils retreated into a pocket that opened up during the creation of everything (sun, world, animals, universe, etc) outside of heaven.
This of course, became hell.
To make this short, after spending eternities in hell, civil war broke out as fallen angels divided into factions right around the time of a new milliennium (which carries much significance in the game...as does the influence that Lucifer had on the events that unfolded during World War 2). Although Lucifer survived, he was unable to stop a massive exodus from Hell that resulted from the war.
Jumping past alot of important occurences...I can tell you that the factions established themselves within the social world of humans. Each faction carries their own secret agendas, yet each faction walks the "edge of a blade" in keeping prophecy from unfolding. Out of a desparate need for surival, the factions separate into two groups battling to control not only their fate but...unbeknownst to man...their own prophecy and progress toward Armageddon.
Well, that was a short enough description but it doesn't come anywhere close to revealing the incredible gaming environment, the politics between and within factions, the progression of "the war", or so many other things.
I will write a few of the other gamers that I know test played the game and turn them on to this site. Maybe they will give some more insightful answers.
Creations End is a fun game and definately brings out the best elements of the genre.
