This post says absolutely nothing.
This post say says a little bit, but I wouldn't classify it as accurate. Sure, there aren't live NPCs outside of Grahm, but there are plenty of questlines to follow, enemies to fight, lore to find, weird things to encounter, and and ways to customize your character out of the gate.
If you want to judge both games on a content volume basis, Fallout 76 clearly has more varied things to see, do, and find than Anthem. How Fallout 76 looks isn't a big deal to me; I'm playing the game on a baseline PS4. And speaking of the PS4, if I played Fallout 76 on launch day, friends online would see I was playing Fallout 76. If I were playing Anthem, friends would see I was playing Dylan (Working Title). (How the hell did that happen?)
