OK, today my rant - copy protection mechanisms used on game CDs and DVDs which mean that you have to have the game in the CD/DVD drive in order to be able to play it.

Copy both the ACF file and the game folder to the appropriate Steam folder on a different PC and when you next start Steam, you'll find the new game listed.

Protect your PC and your hard disk. Right now, you can get a lifetime license to EaseUS Disk Copy for half off $59 at just $29.99.

One company did. Datel, a British company that produced the Action Replay, the ‘Game Genie of the GameCube’ figured out how to get around the GameCube’s disc protection.
