[quote name='electrictroy']Then how come so many games are filled with bugs? And why does my Windows XP, even freshly installed, keep rebooting every 15 minutes? (Don't worry-got it fixed.) I suspect if bugs were found in Perfect Dark Zero, they would have just said, "Oh well", and shipped the game anyway - perhaps with a "fix-it code" made available via Xbox Live.[/quote]
Because "no bugs" in the certification means no major bugs that cause the game to crash or anything like that. Your Windows XP probably rebooted due to non-compatability issues between hardware or a virus or two. It's almost impossible to get rid of every single bug in a game, but getting rid of the major ones are more important before working on the minor ones, which they try to fix as many as possible before they have to send the master copy out for production.
[quote name='electrictroy']Did it? Or did it fail 1 or 2 verifications, but a hihg-up manager like Bill Gates decided to stamp "certified" anyway? I know how these things work in the engineering world. "It's almost perfect - we can't fail it, or we'll lose big bugs - let's pass it even with the flaws."[/QUOTE]
"Games that fail, even in the smallest detail, are sent back to publishers and developers for changes." Somehow I doubt they'd look the other way if it failed any part of the test. If the game failed parts of the certification, there'd be no way that they'd ship out faulty discs and make the launch worse. Plus, Bill Gates isn't really all that involved in the games/Xbox division as the actual higher-ups for that division would be making that decision and I doubt that they'd have shipping out faulty discs just to get them out when they don't need to make that kind of risk if it did happen.
