Ryozo Tsujimoto: This is the next main Monster Hunter game. Our Osaka team is working on it. We've brought in some people who are more familiar with next-gen technology to come in and help us adapt it for the current generation of consoles. When you have a series that runs into the higher numbers, I think the numbers themselves start to become off-putting. New players might think, "Oh, I've missed four games already, I can't possibly join at this point." Just because we've taken the number off the title doesn't mean it's not a main Monster Hunter game. We just wanted to have "world" in the title because it speaks to the concept of the game in a variety of ways. This is the first simultaneous worldwide release for the game, and the servers are global this time.
