Games that do not work without the Internet

If you've played any of the newer games companies such as EA and Ubisoft like Assassin's Creed 2, Silent Hunter 5 or Command & Conquer 4 know that these games require a constant Internet connection. To order any of these three games is not enough function to be connected to the Internet only at the beginning of the game, but connections must be constant. If you just take your ethernet cable or your wireless connection module lost connection to the server just stops and the game is no longer possible to play. If you this seems unfair You're right but it is part of the propaganda that aims to convince players that online presence in the single player games is necessary.
