Yes, he is also a gamer.
But we play only sometimes together, because we both like to play at our own pace. But since a few years we started to play some games simultaneously, so that we actually can talk about our impressions, our decisions etc.
But there are some classic games we actually play in Coop or VS... like Unreal Tournament 2004, Halo: Combat Evolved or FreeSpace 2 :D
Also we played through some Coop-only games like Operation: Tango, A Way Out, It takes Two or the Army of Two series.
AquaNox: The Angel Tears. Mostly because it was complete, but failed Sony's licensing process the first time because it had some logos and graphics in the wrong resolution. And JoWood actually cancelled the whole game because of this.
Also anorher candidates that were cancelled only weeks from Release are Star Trek: Secret of Vulcan Fury and Babylon 5: Into the Fire
