In the Uncharted 2 end credits, developer Naughty Dog thanked fellow devs like Insomniac, Ready at Dawn and Sucker Punch — all three of which have close relations with Sony and Sony platforms.
The two names that stuck out in the thanks list were Bungie and Infinity Ward.
Bungie stuck out because corporate structure has made it such that the company has traditionally only developed for the Xbox 360. Modern Warfare developer Infinity Ward makes multi-platform games, so it wasn't such a big deal to see them — more like, oh hey, Infinity Ward!
Naughty Dog's Neil Druckmann explains the end credit list in a live chat with fans: "We try to be quite open with our technology and our process. We exchanged technology and ideas with other developers. We wanted to make sure we thanked everyone that helped us out in some way."
Naughty Dog? More like Really Generous And Good Dog.
