Fallout 4's gunplay and (some of the) gameplay are the best of the series. Hands down.
However... pretty much everything else? Let's talk about it.
The story is nothing to write home about. It takes a gigantic step back from F:NV in regards to that. There's literally two endings and that's it, whereas compared to F:NV there are several; choices actually matter in F:NV. And the actual "threat" in Fallout 4 isn't really that interesting nor intimidating.
The companions are fine; base building isn't necessary and is incredibly tacky, so I'd honestly not do it at all because it makes no difference. Mr. Preston Garvey (one of the first guys you interact with) is annoying as hell, hence why he's a meme.
The voice acted protagonist wasn't asked for; wasn't needed (clearly trying to be games like Mass Effect; the difference being a voice acted protagonist was there from the beginning...)
The crafting system is fine and somewhat welcomed, although you can go without it. I did pretty much for my first playthrough.
Overall, it's a fun game purely from a gameplay standpoint, but is overshadowed by many things that make it a bad Fallout game. It's a good game, but as a Fallout game? No.
