We’re a bit late to the party now, but there’s still a few hours left to go: Bethesda gives away Morrowind for free today (March 25th), and only today. You need a Bethesda.net account to get the code, otherwise it’s fully free!
Get it here before it’s too late!
Remember that you need a copy of Morrowind to be able to play Morrowind through the OpenMW and/or TES3MP engine, so if you don’t own Morrowind yet, this is a perfect chance to get it for, well, nothing. 🙂
