- Converts PC gamers to console

- Teaches legitimate consumers how to crack a game (when you struggle with it enough you will eventually learn how to defeat it)

- Installs Spyware and other things you never approved of onto your computer.

- Requires an internet connection to install single player games.

- Limits the ammount of reinstalls you can do. (PC gamers never have to reformat harddrives, install new hard ware, have a total OS crash. So what harm can it do¿?)

- Encourages piracy

- Is sometime IMPOSSIBLE to remove, not kidding, some codes are too deep into your computer that you can't delete them.

- Runs more opporations on your harddrive, slowing and sometimes crippling performance

And ontop of this all they never forewarn you that they put this in your game (you only can find out through forums). They should reserve a small space on the back of the box next to system requirements what this games DRM will do to your computer.
