Here's the deal about Fallout 1st:

Should its features have been in the game in the first place? Yes.
Are they just money hungry since they already get plenty of money from the Atmoic Shop? Yes.

With that being said, 1st's features are not necessary to play and enjoy the game casually at all.

If you do get to the point where you could use them, you have most likely already spent dozens of hours in the game and you actually don't mind giving Bethesda extra bucks. Again, should its features have been in the game in the first place? Absolutely. But all I'm trying to say is that at some point, the number of hours you put into the game exceed the traditional ratio of price/hours and you kind of want to support the game since it's being constantly updated with new content.

Just my two cents as someone who has spent stupid number of hours in the game across platforms. Please don't soyjak me.
