Hmm, didn't somebody just admit to pirating JK1 and then demand to know where to buy it?
Sigh... people never listen. These games are still being sold, and yes, you can find them anywhere in the world.
(and you don't even need a CC!)
Or the bargain bin of your local software store/game/hobby shop.
I've seen Dark Forces for like $9 (win9X version which is just a custom launcher for the CD-ROM dos version) in a jewel case.
