Poser isn't used in profitable mainstream CG game design. Game companies hire people who create original, low-poly content, using 3dsMax, Maya or XSI to animate the characters. If I were earning a degree for CG games and they wasted time on Poser I would want my money back.

The main connection between Poser and computer games is that some Poser merchants use the creations of game designers as “inspiration” for product design.
