Haven't played either yet but plan on getting The Outer Worlds on P.C. at somepoint, probably when all the DLC gets released. Will hopefully give me an experience three Fall Out games have failed in doing_
As for which one. What do you prefer; an Action RPG or a Looter Shooter?
Personally I have no love for Looter Shooters, same reason I never bought Destiny, those kind of games seem very shallow and boring. Though I'm sure it has its audience.
