Well, its entertainment. Not a whole lot better or worse than the rest of it - television, film, etc. In an ideal world our entertainment would have deeper messages in it, such as about the value of friendships, dedication to higher causes, creating a great marriage - but I guess making a video game or film about that is a lot more difficult than creating a game about blowing **** up.
I wouldnt worry about it too much; I would more be concerned that you maintain a good work/life/faith balance. Excess entertainment takes you away from your family, from developing yourself further, and from creating a better tomorrow. All things which will provide long term satisfaction, fulfilment, and ultimately, help you do Gods work. Something sitting in front of a PC or TV wont do.
Reading and studying is of greater value (depending on what you’re reading, ofcourse) as that is teaching you new information and further skills.
I say this as someone who spent several years of their life after school doing nothing but playing video games 12 hours a day. Every day, for years. I broke out of it, eventually, and got my life back on track - but I did learn these pursuits have little to offer you but taking your valuable time from you.
