There are people on this forum that think New Vegas is better than Fallout 4
Fallout 4 has much better combat but New Vegas is a much better Fallout game.
Why qualify it? New Vegas is objectively better, just not in every way. Honestly, they're both piss poor "Fallout games", but New Vegas is a fun game with compelling characters and lots to do, where Fallout 4 is a small grey empty world with a small handful of interesting plot points or interesting people.
When New Vegas came out, some people complained that it should have been a DLC, not its own game. Really though, Fallout 4 feels more like a DLC than anything Bethesda has made since Dawnguard.
