Hideo Kojima, the leading developer working on the Metal Gear series, says that he might create more spin-offs, similar to the recent Rising: Revengeance, as long as the company has a clear view of how they can appeal to gamers.
Apparently, the Boss might be the next character to get his own title.
Kojima is quoted by VG247 as saying, “That’s something I want to make personally, but as far as a series of spin-offs – there may be another Rising in the future, but it’s not something I want to make a habit of.”
Metal Gear Rising: Revengeance is focused on Raiden, one of the minor characters of the series, and is more interested in quick action and in adrenaline than in stealth movement.
Kojima is working on Metal Gear Solid: Ground Zeroes.
