I would say as long as it's not interfering with the rest of your life, it's perfectly fine. The breadth of quality games available in this era is really remarkable. To be able to explore that universe and have real experiences is perfectly worthwhile.

Where I think it becomes problematic is when the focus is on exactly one game, especially ones with online gameplay with toxic communities. In those cases you should ask yourself if you might be part of the toxicity cycle (not always the case, but worth some introspection).

I don’t think video games are a problem as long as you have a good, balanced life outside of them.

If all your friends are from the game and you don’t socialize much outside the game and necessary things like work/family, I’d say that is a bit of a problem.
