My childhood best friend was addicted to playing League of Legends when she was in her early 20's. There were times where she would literally game all day, and barely eat anything let alone brush her teeth, take showers, etc. I went over to her house when she moved back with her mom to our home town, and she didn't want to chill she just wanted to keep playing league of legends. She acted like a child and threw a bit of a tantrum, I was going to head back home but her mom insisted that I stay probably to try and get her off the computer. It was awkward, we didn't do much of anything since I could tell she was wanting to get back to playing league of legends. Her mom eventually kicked her out of the house since she didn't have a job, and her ex boyfriend came from out of state so she could live with him. She eventually got together with another dude, got a job and now she still plays games but she's not as bad as she was when she was in her early 20's. She's 31 right now, so I'm glad she got help for her addiction. Needless to say if you see anyone starting to neglect their health and constantly playing games they're most likely addicted and need help.
