Many people spend hours on hobbies they enjoy, and many people spend hours watching TV. Both are enjoyable and also a way of escaping, relaxing, calming the mind.
It sounds like you truly enjoy the games, so enjoy them

If you want to limit the time you spend on them, maybe think of what would be a reasonable amount of time to you, then set an alarm clock or other kind of timer to remind yourself that this is all the time you want to spend on this activity. Have your next activity planned, such as taking a walk or something else that you want to do.
Good luck!
