Ironpoint, stop trying to make yourself sound important as a level designer.
Is level design important? Yes. Is modelling important? Yes. But they are much more replacable than the actual design. More cooperative decisions go into the design than the animation. Same with music, which is why a lot of the musicians work as freelance.
And I consider a lot of the code to be part of the design. Design requires much, much more hands on work with people. It's much more sensitive work, with people shooting ideas down like crazy. If there isn't trust, or one main decision maker, that falls apart as feelings get hurt. And you can't just lump that trust together.
Designers, producers, and main coders are like upper management. You want them to stay the same. You need them to stay the same.
Also, your claiming that AAA movie projects never blow up and fire everyone is way off topic. Of course they don't, triple A movie projects cost over a hundred million dollars. Directors know that, if the movie falls apart, they never work again. Studios know that, if the movie falls apart, they get nothing back. You often hear about major actors storming off. You often hear about major movies being pushed back 6 months to recut it. But the studios are willing to invest another 20 million, if need be, because the movie has to be released to get that $130 back. They can explain an unsuccessful movie and recoup losses overseas better than one never released.
