It's the copy from the July 2000 PCGamer disk (I was looking through my old disks a bit ago so I knew exactly where it was). That disk contains "12 COMPLETE GAMES Plus ... the Daikatana demo!"

Alone in the Dark
The Secret of Monkey Island
Duke Nukem II
Links: The Challenge of Golf
Descent
Terminal Velocity

Road & Track Presents: The Need for Speed
Plus the EXCLUSIVE Daikatana demo! "Experience John Romero's opus on four maps in single-player or co-op mode. See for yourself what the buzz is about."
