Any one know if the following games require a cd key?

[pontifex]

I have a bunch of old PC games that I want to sell but I don't have the manuals for a lot of them any more. Some have the CD keys on the case but I have no idea if the ones that don't show one require a key. I don't want to sell them to someone without a key.

Knights of the Old Republic
Frank Herbert's Dune
Battle Realms
The Wheel of Time
Arcanum
Red Faction
Enter the Matrix
Morrowind
Black & White 1
