Depends. I'll give you my perspectives as to why I quit gaming [ I used to play videogames all the time since I was 6 to about 20.. and Im 21 so yea thats about 70% of my life].
Coding - Coding itself is playing God. Whether you have coded a game before or not, you have to create "space" or a world for the mobs[mobile objects], obs[objects], and procs to work[things like gravity, etc.]. You are in essence playing God. You also decide someones fate if you are coding rpg games. You decide who lives in the story, who dies. What happens to what people, etc.
However, my personal stance is that if you are coding a game that is like, Tetris that it isn't playing God. It isnt creating an actual world etc. etc. I may be wrong, but that is just my perspective from coding [ I used to code for fun by the way ].
Sins - I wouldn't play any videogame that contains sins. For example, don't steal in a videogame or kill, etc. etc. Just because it is a videogame doesn't mean the act still isn't sinful [many will disagree with me on this, but however if you look at it it will just desensitize you to the whole issue of those sins].
Addiction - I dont know about you, but I got addicted to games fast. Whether it was Street Fighter and I was so focused on training my abbility to perform moves perfectly, or Gran Turismo to unlock everything and make all my cars perfect. Videogames can make you addicted, which is a problem.
Thats my perspective on videogames.
