Update monday Jan 16 - 2012: We have been contacted by bluebyte over the weekend, the company that developed the Anno series. Our key has been pretty much unlocked allowing us to properly work on this article. To be continued ....
Uh, NO, NO, NO! Ubisoft and other vendors will continue this trend of archaic stupid DRM until it hits them in the wallet. The 'review' industry should take a stance - no reviews, no press, nothing, until Ubisoft (and any other vendors that do this kind of shit) stop the excessive DRM.
Do you really think the developer of the game will give out an 'unlocked' code to anyone OTHER than a high-profile website reviewer? What if you ran into this at home, which with a grand total of 3 registration attempts, is easy to do over the course of a short period of time: "When contacting Ubisoft marketing here in the Netherlands, their reply goes like this: 'Sorry to disappoint you - the game is indeed restricted to 3 hardware changes and there simply is no way to bypass that. We also do not have 7 copies of the game for you'.:"
THATS what average joe-user will get, a simple 'tough shit'. STOP REVIEWING THEIR GAMES
