If you're looking for a way to pass the time this weekend, The Division, Ubisoft's ultimate game of destroying the village in order to save it, is free to play until Monday. 

The free weekend actually started yesterday, so you can dive in and make with the shooting anytime you like until 10 am PT/1 pm ET on September 17. You'll need Uplay to take part, which you can download here. Any progress you make during the free period will carry over to the full game should you opt to pick it up. The freebie covers the full base game, but not any DLC content—although I can't imagine that will be an issue if you're just getting into it.
