Re: Ah, warez
Blame lazy DRM devs, not the warez scene for that though. Thankfully in most cases, it's trivial to apply a crack that both allows your virtual drive to work, and ditches the need for the optical media.
I've applied many cracks to games I legitimately own over the years - mainly to stop me either having to dig around for the CD each time (just to prove I own the game), or to enable me to take a laptop with a few games on it when I travel.
