I figured this would be the case, but after an ill-fated outage left games frustrated at trying to snag a free PC copy of Morrowind GotY Edition today, Bethesda has extended the giveaway through the weekend.
Originally, the free giveaway was to only last through the end of today, but after having a near four hour outage that impacted many people's ability to download, Bethesda made the right call to extend the offer. The game normally retails for $14.99 and is currently on sale for $7.49 on both Steam and the Bethesda.net store, so its not a huge financial hit to the company to keep fans happy, so its good they did the right thing.
