Kids, if this is your idea of fun, ask your parents to buy you a power washer and go door to door offering your services. At least make some money doing it.
People aren't playing it because they thing power washing is fun. The people that enjoy these games like them because they like seeing things clean and organized. Something that they struggle to achieve in real life. The satisfaction of completing something 100% is euphoric to some people.
I feel you. Honestly it's weird to me that I enjoy this game, but sometimes I need a bit of white noise and the feeling that I'm getting something done. Also I'm sure my knees would give out after a few days of physical labour.
