I was completely blown away after I first witnessed Half Life 2 and Valve continues to amaze me with their Portal series and VR in the form of their HTC Vive, soon to be Valve Index VR =D. I play lots of experimental games, but also completed Doom 2016 which really took me back to my love of shooters growing up. I LOVE that now almost all my favorite old games like Mass Effect have come to PC as well.
