There was some discussion last month about the proposed DRM for Mass Effect and Spore that required the game to phone home every ten days. They backed down from that, but have left in that a user is only allowed 3 activations per license key. A license key is burned up when the O/S is reinstalled, when certain hardware is upgraded (EA refuses to disclose specifics of what), and possibly when a new user is set up in Windows. Only in its first month, some users are already locked out of their games from trying troubleshooting techniques to get the game running.
