Farcry started of in the tropical carribean setting and did for the next three games I believe to finish off the first story. Farcry 2 and Farcry 3 we might call it are both in africa.
It will not be part of 3 so then what location would you like to see for the next instalement after the sequel of Farcry3.
Afghanistan / Pakistan would be the next plausable location for Farcry4 should they extend the Franchise central America might be plausable. The story like should be set realistically in a location.
I know this might be 7 years away or more but i understand you might be planning it as we speak and location matters.
