There's no perfect game, there's no perfect crack, there's no perfect life!
If your kid has the
nasty habit of lifting DVDs from the floor by dragging it around then it's your fault as a father not teaching him to avoid doing that.
That way you'll never have problems with securom or any other kind of protection games.
Although, many games are released now with online-activation. That should makes you happy (unless your kid learn a new bad habit
)
Anyway... you can try to create images from you original DVDs instead of cracks.
