I don't think I really much care where the plot of AC is going, I am more interested in seeing what time periods and locations they will put the games in and how they will tie that into the overarching conspiracy. At this point I keep buying AC games because I like the nominal historical sandbox and feel that the gameplay is good enough that I am not really bothered by its' stagnation. I like how the AC series has continually tried to create nuanced depictions of each historical era (from showing the Crusaders as hostile invaders to the American settlers treatment of native Americans and the prevalence of slave trading during the early 18th century) while not getting into my face about "the message".
