I am currently under heavy temptations and would like to discuss this topic.

When I think about it, it is quite odd that it is so normal to 'kill' others in video games. Sure it's not really murdering someone one but it just seem a little odd, even in movies it's become so normalised. Now there is a certain difference between games where death is depicted very gory, verus not so. Obviously games that have sɛҳuąƖ relation content or simple inappropriate dressed characters should be avoided due to the occasion of sin. But is it wrong to play games if they have some depiction of killing?

As for my temptations;

Over a year ago I made the decision to stop playing video games in-order to be closer to God, recently I have been tempted to play games again and the temptation has been very strong. I mainly used to play a game called 'Destiny', a first-person shooter set in a mythic science fiction world, which starts with your player character is being revived from the dead by a 'Ghost' ("a small, sapient machine created by the 'Traveler'" ("an ancient and immensely powerful machine entity") using the power of 'light' ("also known as the Sky,[1] is a paracausal force (effectively 'magic', it is a video games)[2] that is associated with the Traveler. It is the direct and opposing counterpart of the Darkness).

At the time I was still a recent convert to Traditional Catholicism and took quite an extreme route following some of the material from MHFM and others related to their group, I am also scrupulous (not a much as I used to be). When I thought about the narrative concerning the game I was worried that it might be idolatrous/blasphemous to play so I quit. 
The in-game story has always been garbage from day 1 so it wasn't why I played the game, the main reasons I enjoyed the game was because I enjoyed the game-play mechanics, the RPG elements, and was decent at the game and it was basically my only hobby i.e for fun.

I have been recently tempted to go back to playing the game as an hobby. I know most users of CathInfo have much more experience in life and Catholicism than me so I will appreciate the responses and advice you have to offer. Thanks.

Why don’t you start a hobby or activity which would be good for your physical health and for your soul? You do say that your present activity has been garbage since day 1.

Go bike riding, hiking, walking, reading good books (not garbage), Woodworking, writing, learn a useful skill, take a course in public speaking, learn a new language. The choices are limitless.

Remember God gave you limited time here on this earth. Use it for your own betterment and the benefit of your fellow man. You will be judged on how you used the time He gifted you.

I too have been tempted to go back to video games, but it is just such an unproductive waste of time. Now I can too easily pass much time meditating and thinking on various things both of the faith and not. At least it is much more productive to review the faith and modern errors, to practice the use of reason when meditating on God and creation, and planning ahead for life and solving problems in daily life.

Sigh.  Talk to your confessor.  A traditional Catholic priest.  Don't just field opinions for practical moral questions on a public forum.

Video game violence strikes me as more or less a non-issue, in terms of Catholic morality.

This brings to mind my opinion that there are many things that may be non issues and not sinful that we still should not do, say, or even think let alone will, but that is probably in the realm of nit picking what it perfect and prudent.

If you do play video games, resist playing the usual triple A titles-- for at least a decade these games have been designed as propaganda alternate realities. Even if they're not technically sinful, they're a drain on the soul and will probably cause an anxious and depressed disposition as you go through your life just waiting to get back to the game. Opt for minimal graphic strategy games which stimulate your mind more than your senses, and indie developers who are (not guaranteed, but at least more likely) to be making games that aren't designed to corrupt your mind.

This is very true.  Most of the big game companies are controlled or heavily influenced by various "deep state" elements that have agendas.

Now, the problem is that if you are like some and go back to gaming, that, if you're liable to being addicted to it, soon you could find yourself wasting many hours a day where you could have been doing something more productive and more for God's glory.  That's why alcoholics can never "just" have one drink.  As soon as they take their first sip, they tend to fall off the wagon.  Same thing is true of many gamers.  If that's you, where you would not be able to limit yourself to just an hour or two per day, then it's probably not good for you to start back up.

This, and Nadir's response are the best in this thread, in my opinion.

The reality is that just about ANYTHING ELSE you did instead, including "hanging out" at the Mall, would be better for your body/brain/future. At least hanging out with gang members would increase your social skills, awareness, motivate you to get in better shape, perhaps increase your self-defense and fighting skills, etc.

My point: anything else you could do (not involving a screen) would AT LEAST involve being in reality -- even if you sat on a lawn chair in the front yard and thought about stuff for 2 hours instead of 2 hours of screen time. At least the former would allow your thoughts and brain to develop, allow for meditation, be a true chance to rest and recreate, etc.

Do literally anything else involving your body and real life -- that's my advice. And my favorite quote "only boring people get bored". Likewise, only boring people need to reach for a screen offering canned, mainstream, passive entertainment. A truly interesting person would have dozens of things he wanted to learn, explore, and do.

And some guys wonder why they're not married yet -- why would a girl want to marry someone who was completely uninteresting, and whose life was a total drag? Who would want to be a part of such a life? Make yourself an interesting man, that any wise or smart girl would WANT to be a part of. You'll be much happier in the long run.
