Another fix is BUYING the game.
Some players (like myself) like to throw optical media as far off the planet as possible (low quality, low durability, low speed, bad drives etc. etc. etc.), when games get released on USB media or anything similar I wont ever use a crack, but until then...
Of course, there ARE a lot of real pirates out there (yarr) but don't assume 100% of all the ppl using a crack are.
