I think the first two are more depression. #3 is addiction.
All are a problem - recognize them as such and seek ways to correct. I think actual therapists have gotten better about taking shit like this seriously. If you can't afford that, I'd shoot for some kind of hobby (especially one with a social component), but with the understanding that those can murder your time management as well, so proceed with caution.
Weirdly, I'll do the first two points from time to time. But for me, it's not depression. It's just that I don't like video games anymore even though I did as a child. Occasionally I'll try playing one to hope to get back into it, but it never really pans out. Video games are just too much like work to me, but it's such an easy and relatively inexpensive "hobby" to pick up that I try it now and then. Never really ends up panning out but such is life.
Regarding the "no particular game interests you" part... Holy shit does it feel good when a game genuinely interests you. Lately, I've been doing chores or errands or having a tough time at work and in the back of my mind I'm like "omg I could be playing Jedi Survivor right now and I'd be having the time of my fucking life, but instead I'm dealing with this fucking bullshit." I don't get excited about a game like that very often anymore.
Usually things like this aren't a problem unless they're a problem, i.e. causing the player issues in the rest of their life. If you're choosing games over relationships and responsibilities, that's a problem. But if they just prefer games to other things, that's not enough to say addiction.
An addiction is defined by two things : first, it has negative effects on your life. Second, trying to stop it makes you miserable.
Food for example is not an addiction, it's a biological need. The need for socialisation is another one.
Video games can be an addiction. But I'd argue that they're usually not, they usually a coping mechanism. When they are, the problem is elsewhere, and the video games are helping you to survive through the problem.
Everything can be. But for the largest majority of people, eating is normal, eventhough it can seem to have some aspects of an addiction.
And the most important part here is that even if you somehow get addicted to food, you cannot simply stop eating. Because you need to eat for your survival. It's a biological need.
That's the point of the example : showing that something you can't stop doing is not necessarily a bad thing. The details are very important when it comes to addiction.
And video games are unfortunately victim of propaganda when it comes to their dangers.
In medicine I was taught a number of times that diverse addiction disorders are largely defined one thing: persistence of a behavior despite negative consequences. An addendum is difficulty in cessation of the behavior.
Depression. Concealment of behaviour and time spent in the game. Withdrawal from normal social relationships. Prioritising the game over other activities such as self care, personal hygiene, etc.
In my (small) experience, people can often be addicted to a specific game rather than to gaming in general. Especially with how games these days are designed to be as addicting as possible because MONEY. A big tell for this kind of addiction is an inability/unwillingness to try new games, even if they're in a similar genre.
you spend thousands on equipment, and more on games, dedicate a corner of your house to it, cant imagine that a person can be happy without your addiction, spend hours every week on it, regularly shift conversation between friends to the subject of gaming, etc
