The critically acclaimed (and touching) adventure, To the Moon, is celebrating the holiday today with a 66 percent off Steam sale. The price of the game has dropped to $3.39 - when you start comparing your various favorite pastimes, picking up To the Moon is just about the best emotions-per-dollar deal you'll find.

If scares-per-dollar is a more valuable metric to you, then GOG.com is offering up 1998's classic Sanitarium for just a few cents more, at $3.99. It's also about memory and psychology, but it's a little less touchy-feely, and a little more grabby-stabby, if you know what we mean.
