Thank god for this thread. It reminded me why a job in strategy and biz dev is a lot more tolerable in the games industry and made me to put in rest (again) my ambitions of developing my own title. Having wathced close the development of a AAA title and the über-ambitious Producer almost burn out, I know I could do it but know now better not to go that way. Although he managed to do a truly revolutionary game, it still isn't worth the sacrifice.
Seriously,in the games industry it pays off big time to move to marketing, strategy or biz dev. Sure, there is always madness before E3 and during Sept-Oct, or before a big game unveiling, but nothing close to what I've read in this thread.
As for management consulting or investment banking, having worked your ass off as a junior at McKinsey, BCG or GS you are pretty sure to land you on a comfy Powerpoint job in a blue chip company. But working your ass off as a tester at EA, not sure if that'll land you to a similar position at the publishing side there.
