You forget two important facts Cowabanga:
1. If a game is really as good as crysis or Far Cry it will bought.
2. Not everyone who load and crack a software would absolutly buy this software, if no crack are available. Some only test the software and would never buy it.

The thing is today its possible to load every game ever developed.
Games are very expensiv and become to be smaller, less extensive and have more and more bugs in it.
So I also load games sometimes. After I played a cracked game their follow one of two possible situation:
1. It is as good as CoD4 or GoW, you see the developers work and commitment, the story is good(and not only the graphic), the atmosphere and the game is just great, then I go to the next shop and buy the game to play it multiplayer (company of heroes) and support their work and maybe the next part of the game (GoW2, cod6).
2. I played the game for 10 minutes and recognized that the game isnt as good as I expected (like Prototype), it has no story, only a good graphic, a lot of bugs (gothic 3) or it is only beneath contempt.

I know that not everybody deals it that way. But remember fact 1.
