This was the surprise hit of 2015 but it's showing now signs of slowing down. It launched to great acclaim on the ps4 and pc but recently launched on the x1. 

I still play it daily.  Highly highly recommend it to anyone not already on board. You won't know what you're missing out on until you spend a few weeks playing it!

Deserved. The developers work so hard on this game.

If you haven't got it yet you need to.  Seriously it's just so fun to play.
