It's a different game. I go back and enjoy FNV still and FO4 as well because it scratches a different itch. The looting, crafting, settlement construction, etc. are executed much much better than FNV or 3, or otherwise are entirely new mechanics. It's a whole different thing, it's the studio pedigree and franchise the games belong to that allow these criticisms to continue on even when you're comparing games that are radically different beneath the surface.
