Which games do you consider both fun and interesting

Fun and interesting games > fun games = interesting games

Fun games are overrated

Fun is easy as hell to come by, if you want pure fun you can just go outside and have sex, or drive a car, or play a sport with your friends

What games are uniquely positioned to provide are experiences that are both fun AND interesting, in my opinion all the best games of all time are both fun and interesting and by default better than games that are just one or the other since they make use of the medium's entire potential
