It’s the middle of December again, which means that it’s time for GOG’s DRM-Free Winter Sale once more.

And to kick things off, they’ve put the Ultima Underworld games — and Legend of Grimrock, arguably a modern successor thereto — on sale for 66% and 70% off, respectively. (There’s also another bundle of games on sale for up to 80% off.)

Oh, and you can also grab Fallout, Fallout 2, and Fallout Tactics for free today and tomorrow.

So when you’ve had enough of the Shroud of the Avatar Release 1 test for the day, why not click on over to GOG, spend a pittance, and furnish your software collection with some (more) great games?

The First Age of Update: And the sale is on again, today, as GOG re-caps their first week of sales.
