For more game deals, we'll be continuously updating this Black Friday PC game deals list throughout the week.

Tuesday be damned, GOG has kicked off its Black Friday sale with deals of up to 90 percent off on more than 300 games, and a free copy of Starcrawlers for spending $15 or more. Or you can just go straight to the free stuff with MDK, the third-person shooter from Shiny that's yours for the taking for the next two days.
