Sid Meier is known as the mastermind behind some of the most respected and influential video games of all time, such as Civilization, Railroad Tycoon and Pirates.
But in his pursuit of conveying a realistic experience for players, he says his logical mind wasn't taking into account enough what was going on in players' heads.
"Gameplay is a psychological experience," Meier acknowledged during his GDC keynote. Today he is director of creative development at Firaxis Games. "By acknowledging that gameplay is actually a psychological experience we ... can end up with a better game."
