An article at the Official PlayStation Magazine website has an amazing piece of news, headlined "Hideo Kojima remembers Metal Gear Solid 1." Not only does he remember it, but he seems to recall actually being involved in development.
“It was a very pure experience,” Kojima said during one of his lucid moments. “I was just making the game I wanted to make. Looking back, there’s not anything in particular I want to go back and fix. If you change anything, you change the game – and I want to avoid that. If you bring the gameplay up to modern standards, then you lose a bit of the original game. It was a game made for a certain era – not just the story, but the controls and everything about it reflect that era in which the game was made.”
After getting confused by a paticularly interesting squirrel, Kojima managed to get back on track – bless him – and started discussing the potential of a remake.
“There are a lot of people wanting remakes of the original, and as producer I want to answer those calls” he continued. “But as a creator I’m not very interested in going back. If we were to do it, it would have to be a total remake – the only thing that would be the same would be the story. If it happened at some point I would stay as a producer, but would have to hand off most of the actual creating.”
So there you have it, expect a Metal Gear Solid remake whenever Kojima next releases an unsuccessful game. We may be waiting a while, but I'm sure it'll be worth it.
