Every time I get a read error on my CD-ROM under Windows, it triggers a very
low-level fault that manifests itself as a blue-screen. The application
software never even has a chance to recover from the error. With the
current state of CD-ROM drivers, I have my doubts about this technique being
reliable. Can you imagine the outcry of thousands of legitimate customers
who can't run the game they paid $49.95 for because of some oddity in their
CD-ROM drive? I think Sierra would be taking a big chance on pissing off a
lot of people for little in return. I'll gladly pay money for a game that I
like, partly for the value-added in the form of a (hopefully) well-written
manual and decent customer support, and because its the right thing to do.
Those who pirate games do so, in many cases, for the thrill of it, or
because they can't afford the games, or wouldn't buy them otherwise. Its
been said that there are more pirated copies of Windows 95 floating around
(mostly in Asia) than legitimate ones. Do you think Microsoft is hurting
because of this? Hell no! Why do you think they give away Internet
Explorer? In my view, the more people exposed to a game, the better. If
its a good game it will sell well and make money, period. Just ask John
Carmack.
