Steam Free Weekend for Dome Keeper! This is a game I've had a lot of fun playing, so some of y'all might like it, too. I just noticed and it isn't being advertised much so I figured I'd spread the word. http://store.steampowered.com/app/1637320/Dome_Keeper/
Another "this weekend only" thing that I found out by accident. The film Labyrinth starring the late great David Bowie is having a re-release for its 40th Anniversary. It has been remastered in 4K, but is only in theatres until Sunday.
