I myself have four kids, one of them is now an adult and my daughter is also going to be an adult in October, I then have a 14 and 15 year old (going to be 16 in December) and I have always allowed them to play games as they tend to hang out with their friends online and play games such as Fortnite or even Apex Legends.
I found that it helps them to relax and chill out after things such as school and college and they seem to feel a lot better for it being able to shut off in a game with their friends.
Many people feel that too much console time for kids can result in addiction which I believe can in some cases and it's always wise to monitor your kids time on consoles but I have found that my kids will head out, leave the console for a while and do other things and I haven't had to worry about the addiction side of it.
My kids are also all doing well in school and both my two eldest children have completed school with great grades and have gone to college as well. The school my kids go to encourage kids to do what they enjoy in their spare time once they have completed homework and such as they realize it can benefit their mental health.
