Run 3 is an enigma. It is such a simple game that it hardly counts as a way to pass the time. It plays on the basic idea that doing something brings a reward, giving the player a series of dopamine rushes that build on each other. The newest in the series of endless runners, Run 3 challenges players to guide a swarm of small aliens through space and defeat the evil Dr. Eggman. A lot of young people nowadays are really into the Endless Running series of games, which Joseph Cloutier created.
