Tbh I love FO4. It’s not the best in the series, but I’ve played it through a couple times and wouldn’t mind playing it again soon. Hardly anything I’d call a colossal failure. FO76 was a hot mess at launch, but it had its hooks. I got that at launch and ended up playing more of it than I expected considering. No clue about Starfield, but if FO4 and 76 didn’t bug me as much as it did everyone else, I might get on with it decently… assuming they put it on PS5 at some point.
I think Elder Scrolls VI will do well no matter what condition it’s in, though I also doubt it will be a smooth launch.
