Piracy wasent the real problem.
Crysis one was pirated but nowhere near as much as in 20 to 1 ratio. If that was true, no gaming company would exist because everyone of them would cash in and leave b4 piracy destroyed them too.
Estimates where somewhat in 9 million sales, 4.5 million pirated (Here is they key element: from those 4.5 million, many actually bought the game afterwards).
In crysis 2 and 3 sales dropped because it was not a game that people wanted to pay for, plain and simple.
I dont want to get into a debate of crysis 1 vs 2 or 3, but the sale numbers tell the story.
I never even tried crysis 2 and 3, but I do have 3 copies of the original crysis (one in english one in spanish and one in steam).
Personally, I wont cry over crytek. After farcry one and crysis one their games were of no interest to me, and perhaps the workers who left can make a better game without having to answer to the burocracy of big companies.
Also note that you have to take into account the production costs.
I dont know the numbers but im quite sure crysis 2 and 3 costed a lot more (due to advertising mostly) than crysis 1.
Hell, it seems that the higher the budget, the shittier the game... (in some cases at least).
Actually i remember a documentary that proved some time ago that piracy boosts sales of good products and kills bad ones.
The theory behind it was that people who are not going to buy the game in the first place will be able to experience it, and spread the word among those who can buy it. Not everyone likes to have pirated stuff on their PC, for many many reasons.
Those who would buy the game can play it before and then decide if they want to spend their money on it. (at some point it was quite normal, they used to call it a demo).
Of course nothing stops people then from having a pirated game and never buying it, but the biggest problem has always been DRM. Especially the one that crashes the game and makes it unplayable for 1 week after release. Hackers will always find a way around DRM, and their version rarely has crashes, and when it does, those people actually help you solve it.....
Ofc you can get a virus on your PC or similar, but generally, its hard to hate piracy when they are the ones trying to help you run the game, while companies seem to only take your money.
Crysis one for example had a quite simple protection, and it was pirated less than the sequels. The law is also changeing rapidly to ban piracy, wich is a good thing, but im sure that studios making free to play games will destroy big AAA companies when that happens, as it is already starting to happen.
