I played Unreal Tournament for about 8 years solid, and spent thousands of hours making maps for it, but I slowly drifted away from PC games when the original Xbox came out and I got into Halo, then I discovered Need for Speed Carbon, and spent too long chasing world records. I was shit hot on it and all of the Need for Speed games. I even held a few world records, then I got bored and stopped playing on consoles for a few years, and went back to PC gaming, which I gave up about 3 years ago. I didn't touch another game until last year when I bought I bought an Xbox One, which I used for about an hour before getting bored with it, and haven't used it since.
I have GTA V, Hitman, Borderlands 2 and the Pre-Sequel, Sid Meier's Civilisation VI, and a load more I can't remember the names of installed on my PC, and I've never even opened them, never mind played them. I've just completely lost interest in games, but I do that, I go through phases. I'm now in my 3D printing phase, which I'll no doubt get bored with, eventually.
