Computer piracy will not be stopped by the requirement to put the cd in the machine because
1. The cd can copied easily by anyone with a CD-Rewriter. The so called "protection" measures on commercial cds are easily worked around (so I have been told..ahem)
2. There are web sites who make no-cd patches available for download. If the requirement is left on SC 1.03, 1,04 etc. then a SC no-cd patch will be produced for download within a matter of days.
Please please please leave it off!!
