they're just saying EVERYWHERE is a possibility according to the quote. Which is, like, duh. Japan would be neat, but once again the cities of historical Japan would seem to me to be pretty boring from a navigational standpoint. They need to go back to selection periods and times based on how well they would support superior free running gameplay.
But I really want them to go bold for their next-gen outing. I want a game set in EDEN, which has no proper historical context, so that they can go truly wild with the technology and the possible parkour possibilities (PPP).
