Earlier this week, BioWare announced that the PC edition of Mass Effect would require online activation every 10 days for the game to continue working. Obviously this news didn't sit well with fans, as they voiced their displeasure through various message boards. Seeing this reaction, BioWare has decided to change their DRM plans, scrapping the whole 10-day reactivation deal and replacing it with a one time-only online activation, with reactivations only required if you choose to download new content. The announcement and a full FAQ on the changes can be found right here.
Also, Kotaku has word that Spore is dropping the 10-day DRM as well. Score one for the little guys! ;)
