GT Sport and GT7 for me as well.
GT Sport I spend many hours a day on, online racing. My time driven on GT Sport is 3,937 hours over 1209 days and 15,664 online races. That doesn't include all the time spend in the menus and making liveries for tons of cars. It became a problem, that averages 3.25 hours per play session. I did use GT Sport for months as 'pain medication' after I dislocated a rib. I couldn't really sit without severe pain, playing online races standing distracted me from the pain for the duration of the race. Saving the real pain medication to get a few hours of painful sleep at night.
But it stuck and then I had to keep racing as much until I eventually burned out on the game. Which didn't happen till after the transition to GT7 and spending another 447 hours on GT7. The online race quality got me to quit, wasn't fun anymore with people rather playing bumper cars instead of racing. However over the holidays I got back in GT7, finished up all the offline races in VR and now do 2 hour endurance races in VR. I'm staying away from online though.
Another game that became surprisingly addictive was factory simulator on Roblox. So much I ended up with 5 accounts, 3 running on my laptop, 1 on my wife's laptop and 1 on an old PC in the basement. My laptop at the time, running a script to keep the windows from timing out.
Building stuff is addictive, then managing it became very time consuming
Just 2 examples of all the complex stuff I kept doodling together with tons of notes to calculate and implement optimal flow rate
It became an obsession.
Of course still nothing compared to the time we spend on Everquest and WoW back in the day.
However most of these if not all eventually stop being addictive. Factory Simulator was no longer supported and with no new challenges I first started setting myself new challenges, like using the fewest machines possible by timing everything just right
And other kind of restraints or combining multiple levels into a single huge factory.
Yet everything eventually grows old. Everquest became a late game grind, WoW became a late game grind, Racing the online quality deteriorated further and further, updates for games run out or you simply exhaust everything in a game.
But I basically have to force myself to stop playing every night lol. Go to bed.
