I've always hated the end game of Civ's. It's always felt... dissatisfying. Early/Mid game was always fun but if it lasted to the end game, I usually ended up quitting and starting over.
This newly announced game has so many paths it could take and the possibilities are truly endless, if the dev's decide to make it so that is. I had faith, but after Civ V, the Sid Meier's brand has faltered in my eyes.
(i've been playing his games since Sid Meier's Civilization (holy shit that was a long time ago), my favorite, to this day, is still Gettysburg)
