It's Quake. Take it or leave it.
I have routinely come back every couple years since 2005 to play this masterpiece. The GOG version is everything a person could need with this game, with the lack of any multiplayer support outside of a few mod servers that I am not even certain are functioning any longer, all most of us have is the singleplayer. And in that, what more needs to be said. Innovative for the time and amazing even now for its polish and quality. Truly a good old game.
