We’ll get the obvious picks out of the way. If you love everything about the way The Outer Worlds looks, and you haven’t played a Fallout game yet for whatever reason, you should probably get on it now.
Specifically, you’ll want to check out Fallout 3 and Fallout New Vegas, with the latter being regarded as the all-time best entry in that series. New Vegas, in particular, is beloved for the various well-written factions that you can get acquainted with, such as the New California Republic and the iconic Caesar’s Legion.
Fallout New Vegas has incredible NPCs that you won’t soon forget, and it’s definitely the closest thing you can get to The Outer Worlds right now.
Fallout 4’s great as well, but falls just short behind 3 and New Vegas, and is still worth checking out once you’ve worked your way through the other two massive RPGs.
