That's good that you had no issues! I find that the gamepass subscription, especially for $1, is good for being able to preview a few games, I think. And then buy them on Steam if enjoyed. I wouldn't continue my sub for the full price. I've managed to get quite a few $1 deals out of them over the past couple of years, so will just grab that whenever I can.
Fallout 4 is fantastic! In my opinion, anyway. There are a lot of people out there who don't like it at all and prefer to play the other Fallouts instead, whereas I prefer to play #4 and don't really like the other Fallouts. 😅 I've been meaning to try Fallout 76 too but a lot of the recent negative reviews have been scaring me off.
