"Piracy is a real concern. The PS3 has been cracked now as well and people are downloading PS3 games and 360 games are being downloaded so that's a threat to just the industry in general. For us specifically, it was a very traumatic experience because we're really excited about the game and the quality that we were able to get into it and what we were able to accomplish... We're at the end and we're really excited about where we're at and your game gets leaked. And it's not even that the final version of the game gets leaked, you know? People are like 'It's 40/45 days before launch, Crysis is leaked' but that build was already from the middle of January. With 250 people working on a project, thousands of bugs get fixed in a heartbeat. So that version is like a really ugly version that we don't want anyone to see... All this stuff starts going up in pieces and even if someone downloads it and plays it themselves they might make a bad decision based on the fact that there are so many bugs in it. 'Oh, there are so many bugs in the game I wanted to play. It's so buggy, I'm not gonna buy it now.'"
There is also a chance of no more Crysis in the future.
"Crytek has told that it fully intends to make Crysis 3, and that it already has a plan for how the series' story will progress. However, the studio admits that the chances of a third game in the FPS series making it to market depends on the success of Crysis 2."
