I've had to quit all games other than Civilization 5. The games literally wreck my life. Anything with any sort of social aspect, I'm not sure if I can afford to play with other people for the entire rest of my life. I've already spent so much time on MMORPGs etc.
One guy I played with messed up his back snowboarding and had surgery. He would play like 12+ hours a day and you'd just hear him taking bong rips all the time.
The other guy was like super fat 300+ pounds, running an eBay store and was just on all the time.
I would play a lot too but then you would want to kind of step back a little and you'd feel guilty because they were on by themselves playing alone.
You'd hop on in the evening to PvP with them and then you'd get entangled in ingame drama, defending your dungeons, etc etc.
It ends up consuming your entire psyche and you start living your life around it.
I installed Cold Turkey Pro, and started using that to block out all distractions, on my computer at home (Ryzen 1600 with a 1080 ti) and on this laptop (1070 with i7 7th gen), I've spent a ton of money on gaming equipment.
Now I just study programming, youtube. At least the processor is good for Civ 5. Eventually in the future I can dick around with machine learning or something like that and make use of the GPUs. or maybe I can play very high graphic single player games in the future.
Its good to just block everyting off for like 4 hours if you are having a problem being productive and you have long periods where you can use a computer. By the end of 4 hours you will have ended up getting interested in something productive and made some headway with it. After a 4 hour cold turkey block you can often self restrain yourself without need of the software.
When you institute a block, that's it, it's blocked. Can't unblock it until its over. I wouldn't do anything crazy like block it for a week, just like 4 hours. Sometimes you'll do a block and go watch TV until the block is over. That's fine too, it helps train you to stop abusing the computer as a gaming machine and find your entertainment elsewhere in another environment. If you keep doing that you can retrain yourself to use the computer as a productivity tool.
And after a couple weeks when everything goes to crap in term of your habits, you can just start instituting the blocks again. It's like a parent taking away your privilidges. Even if you are in your 30s, you still need that trust me .
