It is true that game addiction can have a bad effect on the health of the brain, but the standards of game addiction are also vague, and people who actually use games as a profession play games for hours, and can you say their mental state is bad? Games aren't the only things that cause brain trouble. Your argument ends up saying that playing games is a problem. I think it's a generalization error to call games a disease, citing brain problems. I think we need to clarify the criteria for game addiction first. This is because there are many healthy people who like to play games.
