Some people can play games from morning till midnight and never gets bored but would still repeat the drills tomorrow.
Playing games is really similar to sports, but somehow I haven't heard from anyone that sports could be considered an addiction. That's just a matter of perception. I know also that games are considered as a form of escapism but that's just speculations. For example, I love playing cRPGs just to chill and my latest passion is Path of Exile. This game is awesome and I ordered powerleveling from this site, don't see anything wrong about it. It saves me time and grants me joy. You should check it out at your free time too.
