Video games are designed to make you hooked and extract as much as they can from you. You are slaves on the world they created, wasting your consciousness away on a virtual world. And the grinding games are the absolute worst, its just the same gameplay over and over.
Video games are designed as a means of entertainment or relaxation. Video games can be educational entertainment. Of course entertainment should not be done excessively so as not to become hedonism. Playing games regularly with enough playing time will help you release stress after a day of work or study.
