There is one drawback to seeing Uncharted 2's co-lead designer, Richard Lemarchand, unfurl the development process behind the most successful and most ambitious game in the studio's history. A post-mortem panel, held on Thursday afternoon at the Game Developers Conference in San Francisco, delved into developer Naughty Dog's pre-production process, its production pipeline and the climactic rush to a spectacular end. It also highlighted some of the studio's misjudgments, which resulted in a difficult crunch time toward the end of development.

And now, every time I play that incredible train level -- "an evil monster of a level," Lemarchand said -- for my personal enjoyment, I'll pull back the curtain and see programmers hunching over keyboards and nodding off into icy cups of coffee. Thankfully, Lemarchand painted a warmer picture, firm in his belief that the development team's intrinsic motivation to produce a character-driven blockbuster helped it overcome the final hurdles.

An important pre-production phase dominated the first six months of Uncharted 2's 22-month creation. "Messing it up often means messing up the whole project," Lemarchand noted. There were no deadlines or deliverables during this period, and the team was free to seek inspiration and consider the individual moments they wanted to explore in Drake's second outing. A single image would portend much of the game's direction: A photograph of the Tiger's Nest Monastery in the Himalayan kingdom of Bhutan.
