I am close to finishing The Outer Worlds. The game has a somewhat mixed reception when it comes up in discussions online and I think it's mostly because the developer Obsidian made New Vegas and Outer Worlds apparently is the worse game. So, I never played New Vegas and therefore can't compare the two. I do enjoy my time with Outer Worlds very much!

• it's basically the same formula as Fallout 4 but in a humorous space setting with better gunplay. Or, alternatively Borderlands with a ton more talking and decisions and worse gunplay. In any case a lot of shooting and looting.
• different builds are possible but not as significant different as in Borderlands. But since it's not a massively big game it didn't matter that much to me. After a couple of changes I kinda kept investing mostly in my handgun, my companions and personality skills to pass more skillchecks.
• what I like: the stories the game tells! Be it the main quest line or quests for factions or your companions. All have a nice sense of humor to them without getting too silly. For example there is a dude in a wurst factory and you get sent there to end whatever he is doing there (hint: it's more than producing wurst from spacepigs). And there are a number of ways you can approach this: guns blazing, trying to sabotage the factory or sneak in and just kill the guy.
• also: great soundtrack and overall sound design! The jingle that plays when you level up is just great!
• also: while not a massive big game there are a lot of different places to go and explore. From abandoned settlements in some sort of desert to a big city where only rich people live and everything in between.
• meh: so many drinks, lotions and food items that give you different boosts. Problem is that there are so many different items it's hard to keep track which one does what. I abandoned pretty much all of them and only kept Adreno (restores energy).
• meh: fast travel can be annoying because most of the time you have to fast travel back to your ship and then from there select another planet/spacestation and then land your ship and then again fast travel to wherever you need to go to. So it's potentially three (not very long, though) loading screens if you need to go someplace different.
• decisions do matter in quests but the general direction of the story is set.

I say: if you like stuff like Fallout, Borderlands and generally combat heavy action rpgs, this game may be right up your alley. And since it's kinda old at this point it's also pretty cheap most of the time.
