All studios suffer a difficult transitional period when a new piece of hardware is introduced. Even the best experience their "darkest days" during this time.
In speaking to Eurogamer , Naughty Dog co-president Evan Wells said the shift to a new generation is a "double-edged sword" and that while the geek inside you rejoices at your shiny new toy, the practical part of you realizes: "this is going to be a lot of hard work." Said Wells-
"When you're going to new technology, every day is a slog, progress is slow and it really takes a different kind of attitude and mentality to get through that kind of push and it's not right for everybody."
When the team was switching from the PS2 to the PS3, Wells said Naughty Dog really struggled. In fact, they "lost people on a weekly basis" because they "just couldn't get through it." Co-president Christophe Balestra added that moving to new hardware is "terrifying" and they made "some mistakes" when they moved from the PS2 to the PS3.
The Last Of Us is Naughty Dog's latest game; no word yet on whether the Uncharted team is cranking on the fourth installment. Some are working on multiplayer DLC; others are just on vacation. Yeah, remember when we said Uncharted 4 might be on the PS4 …?
