I wasted alot of time with games when i was younger .. there really is no benefit to them and they are meant to be as addictive as possible for you to play.. i put them down made some life changes, went out more, worked harder, read books, and also partied meeting lots of women making new friends.. i actually had a entertaining life.
While i wouldn't say games are evil, or they are bad.. They need to have a balance there is so much more to life, and i feel smartphones have the same effect. It's really sad seeing people in social situations just stare down at their phone the entire time. Its reported that people will waste around 2 years of there life on a smartphone.
