GP: "Earlier this week, Metal Gear Solid 5 was revealed, which shocked some and seemed obvious to others. For me, I was sort of in between. Hideo Kojima has, for years, been playing with the idea of ending the series, with pretty much every game in the series planning to be the last one ever. Because of that, I wouldn't have been surprised if Guns of the Patriots would've been the end, especially considering how nicely it tied up most of the loose ends of the series.
The series is complicated, though, and there is always more to be said. There's definitely merit to making a new Metal Gear Solid, but there's also the risk of really, really screwing it up. So what can they do to keep that from happening? Well, like most people who want to achieve greatness, they have only to listen to me."
