ITT: Folks comparing labor hours without cost of those hours.
Folks, coders who understand how game engines work and can make graphically intense well running games are 3.5-4 times more expensive per hour.
I really can't believe I have to spell this out for everyone. Do you really think naughty dog or Rockstar aren't hiring folks at 200k+ to work on these games for thousands of hours only still to fuck out up after 6 years of development?
I'm not saying 3d is better, it's clearly too expensive for everyone to push these boundaries and different tools for different games; but this is just the economic reality.
