I have to be honest, I was never looking forward to a Pagan expansion, it was a shrugged off moment, going "Bleh..", but they really made it appealing by adding tons of new mechanics and best of all, the new start date. One problem I find with CK2 and EU3 is after a while, you simply look and know exactly how the game will play out. With the new start date, even the old areas are worth re-exploring through their new environments. Best of all, England is not united in any sense, which is a refreshing change.
