Assassin's Creed II's most unusual attribute, however, is displayed in big letters on the front of the box: "A permanent Internet connection is required to play the game." This requirement wouldn't be so peculiar if it were an online-only multiplayer game, but Assassin's Creed II is a single-player, story-driven adventure. Whenever you play the game, you must sign into an online portal; if you aren't connected to the Internet, you cannot start the game, and if you lose your connection, the game will pause. Even your saved games are stored online, which is a boon if you plan on playing on multiple computers, but seems like an otherwise unreasonable mandate. This is a bold approach to digital rights management--and one that could unnecessarily hinder your enjoyment. If a storm knocks out your Internet connection, you're out of luck; if you want to play games on your laptop during an upcoming airplane journey, cross Assassin's Creed II off the list of possibilities. And even if you maintain a solid connection, you might run into a few problems. Twice we had the game shut down while it was saving, and we ran into short but noticeable delays multiple times while the game attempted to load our profile and download our progress. Other times, our attempted login timed out, or the launcher incorrectly informed us that we had used the wrong username or password. These issues hindered our playtime for hours, and sporadically affected European players for days. (gamespot)
