Piracy doesn't kills gaming because it helps it a lot, think like this:
companies makes games, some people buy it, one guys cracks it, and LOTS of people play the cracked games ;)
so that's how games get popular, if it was for me, I would never spend money for games, such as... giving 60 euro for cod mw2 or other games, better play cracked SP or MP on infinity ward or another example... 60 euro for cod black ops... better play cracked SP or pay the money for MP ;)
