Assassin's Creed 3 thinks your ideas are stupid and you should just shut up already. Really, that's not even very paraphrased.
"People on the internet suggest the most boring settings," Alex Hutchinson told OXM. "The three most wanted are WWII, feudal Japan and Egypt. They're kind of the three worst settings for an AC game."
Assassin's Creed 3 writer Corey May really wants to do India, and Hutchinson agrees, saying "I would too. I'd really love to do the Raj."
The moral of the story is: Don't expect an Assassin's Creed title in WWII, feudal Japan or Egypt settings, ever. Also, shut up.
