Several of Ubisoft's biggest titles won't be playable as of next week thanks to a server move by the publisher and the restrictive DRM that was used in their development.

This isn't just multiplayer either. Because Ubisoft thought it would be a smart plan to use always on DRM for even the single player portion of games like Assassin's Creed, even the single player portion of that title won't be playable during the server move.

Kotaku has the other games affected in this move: Tom Clancy's HAWX 2, Might & Magic: Heroes 6 and The Settlers 7. The Mac games that will be broken during this period are Assassin's Creed, Splinter Cell Conviction and The Settlers.

Any game that makes use of Ubisoft's Uplay software will also be affected. If your game has been activated previously, then offline play will still be possible - though online won't be - but if you've not activated yet, you won't be able to play single player either.

This move was announced this week as part of a community letter, with Ubisoft describing how the data servers for many of the publisher's online services would be migrated from third party facilities to a new location starting on the 7th February. The publisher didn't reveal how long the transfer would take.

"We apologize to our customers for the inconvenience," the company said. "This move ultimately will help us improve the maintenance of our infrastructure and deliver better uptime and greatly improved services for our customers."

Nice Ubisoft. Integrate something to stop pirates and in-fact you end up blocking people that bought the game legitimately from playing the game. Those people paid money for your game and they won't be able to play it. If you didn't pay, downloaded illegally, pirated, you'll be able to play fine.

Makes total sense, right?
