I worked in QA on some AAA titles and I remember being told that the hours the team was putting in testing the game (nearly 300 people over several months of over time) would be matched by the players in the first 6 to 8 hours from the release. That and when the team is filling hundreds if not thousands of defects daily, how can the dev team keep up and "fix" everything?

Why are developers reinventing the wheel for each release (seemingly)?

The fix in my experience is to build a baseline between the low level framework and the UI, like a business layer in most web applications or the HAL in Windows.

I'm not a game developer though, so just my stab in the dark :-)

They do this though its called a video driver and a video game engine.

I agree with your statement. They can't fix everything.
