Gaming can have positive and negative effects.
On the positive side, it can sometimes provide people with a needed social outlet, at least if it's an online social game.
It can also sometimes stimulate a mind that's depressed and lethargic, giving it a much needed jump-start so to speak which carries over into other productive tasks.
Conversely, it can get you addicted to and dependent on quick and easy dopamine hits, killing your ability to focus for extended durations needed for any kind of productive work. It can also cause mental fatigue that makes committing to or completing non-trivial tasks difficult or impossible.
Gamers have to be aware of both effects, and honest with themselves about which are occurring, and willing to change their behavior if they observe the negative ones.
