If you'd like to play the PC version of Bioware/EA's hit XBOX 360 title "Mass Effect," you'd better have an internet connection. Why? Because in order to remain "activated" the game will need to reauthorize itself via the internet every 10 days. Go 11 days without checking in and your game won't work until you do. Some gamers are saying that this requirement makes them feel like criminals, and doesn't make a lot of sense for a game that otherwise doesn't require an internet connection.
