Damn, wasn't expecting to see that tweet! He's been absolutely integral to Naughty Dog's growth and technical prowess over the years, in my opinion deserves some massive recognition. A lot of Naughty Dog's reputation was built off how technically accomplished their titles always were. Even going back to the days of Andy Gavin and Jason Rubin. Christian and the team really helped push the medium forward.. especially during the PS3 era.
This is NOT a concern or doom/gloom thread! This is NOT meant to be anything other than what it is. Someone who has simply decided to move on to other things after a long service. I just think that it's an important event for Naughty Dog and thus should be discussed.
