Now i am not an expert on the Assassin's Creed franchise, but i have played enough to know what to expect. I never got into the series until Assassin's Creed III. Then i went through and played the rest of the games.
Now when you think of Assassin's Creed, you think of an assassin in old Europe (which is why i never played it in the first place). The newest Assassin's Creed took place in the American revolution, which game the series a new look. Now we're going to be in the Caribbean! Which is probably going to be the best Assassin's creed ever. So where will they go next? Are we going to jump back in time or go into the civil war or (i hope so much) one of the world wars? Then again making an Assassin's Creed that far in the future probably will be changing the idea of the game too much.
