The Witcher 3 - Wild Hunt ~~$39.99~~ $3.99 (90% off)
If you've somehow managed to avoid Witcher until now, it's a dark medieval fantasy, 3rd person, open world RPG based on ~~Norse~~ Slavic mythology. Lots of political intrigue, choices that actually impact outcomes in game. Fantastic voice acting, story, soundtrack, and combat/gameplay mechanics. This is one of the best games on the market - if you don't already have it, now's the time! There are also two DLCs that are each the size and scope of an entire standalone game - don't miss those!
Also available DRM free on GOG for the same price.
