Sid Meier - he's been around a while hasn't he? Rather than being a prolific designer who takes the Kojima approach of slapping his name on every cutscene, Sid Meier gets his name in the game's title. Not out of arrogance, but because his name is so synonymous with quality strategy games that it showing up in the title means that game will shift more copies, and his publishers know this.
Meier is the father of Civilization, and he still oversees Firaxis in its creation to this day. While the series has shifted and changed over the years, it turns out Meier's approach to design has stayed largely the same. Don't fix it if it ain't broke, right?
"Usually he puts up a prototype - nobody know it's coming," senior producer Dennis Shirk tells us at E3. "He'll just come to work some day and send an email through the company saying 'hey, get us all together for a huge multiplayer match'. We'll just start playing something, and it's really cool because he's got his own custom engine that he works in, that he's slowly built over the last 20-or-so years. Then eventually it gets translated into something modern."
So Meier never really stopped working on the first Civ - he's just been polishing it over the course of a couple of decades. The engine is unique to him and he's the only person who knows how to use it.
"He's got an engine he works with because it's just this sort of environment he enjoys," explains Shirk. "And every time he has to do something new for a new prototype he has some other engineers help to plug in new functionality. He could probably write just about anything in this and come out with a prototype. It's Sid's baby."
