I dunno, I hear what you're saying, and I too experience enjoyment from work, but I still play a lot of games on the side. The difference is effort vs reward, in that in my day job I spend hours hacking away for some reward, whereas in games there's (usually) enjoyment all throughout.

Finished another playthrough of Factorio again the other day, each time I learn of my mistakes and improve on things again. This time I made a proper train network and used premade blueprints for it, it was really neat and things went pretty smoothly. 70 hours or so until first launch.
