The Awful Anti-Pirate System That Will Probably Work

However, it's important to always remember that a pirated copy doesn't equal a lost sale. Many people download a game, but never install it or play it. Others download and play it, but if they couldn't have downloaded it, they would never have played it. And finally, there's a percentage of downloaders that would have bought it if they hadn't gotten a pirated version first.

It will be interesting if this experiment by Ubisoft can determine how large that percentage is. It's definitely not 100%, and it's definitely not 0%. I would guess that it's a single-digit percentage of the people that would normally pirate a game that could go and buy it instead.

However, this new DRM is so vile, that they will also lose sales on it, and I wonder if the sales they gain from delaying the pirating of it is larger than the sales they lose from having a horrible DRM.

Office, and plenty of other desktop software will nag you relentlessly until you "Activate your copy online".

This is especially annoying for people like me, who spend months at a time off in the sticks where there may be occasional generator power but there certainly is no internet.

Just a few weeks ago, I "activated" my copy of CodeSmith with 5 days to spare (out of 30). If I had had to make a special trip to a city just to do it (which from the pacific coast of Colombia would have required a flight), I would have been pretty upset with that company.

This means a hacker has to figure out the saved game format, somehow jam into the application new code to write the saved data and new code to read it, TEST IT, and get it to work.

In most of the cases, there is no need to figure out the game format. Just read the binary data sent to the server and save it. Usually save game files are not that large and I suspect that most games read them at once to the memory.

Again you don't have to write a lot of code to do all these stuff. Just redirect whatever is sent to the Ubisoft server to a local server host in the same machine. This way the user can carry the save file anywhere. This is an added advantage for pirates while legitimate users should rely upon Ubisoft to save their game files for them. Heck, they can even play when the Ubisoft server is down, or even if there is no internet connection.

It's easy for Ubisoft to also force the binary to be cracked: have the client request the server sign a random token with its private key, and verify it with a public key embedded into the client. This way a third party server could only be written if the client was also cracked to either change the key or remove the check.
