> It's hard to believe this was just incompetence - Sierra games were technically impressive for the time, making great use of graphics and sound. But what other explanation is there? If Sierra's goal was simply to prevent casual copying, they didn't have to bother with licensing Superlok at all, a simple bad CRC on one sector would have sufficed. It's all very odd.

It's not odd at all, if you think again about this:

> Softguard Systems was founded by Joseph Diodati, Paul Sachse and Ken Williams in 1983

Obviously it's not Ken who implemented the copy protection.

(ofc if this that Ken at all)
