It’s a bit early to judge this from the supposed leaks Umiman posted. All we know for sure is that it won’t be a mainline RPG, and is set ~20 years after the bombs fell. Which is fine, since it’s not like this is instead of Fallout 5.
The stuff in the spoilers is full of contradictory information. Spoiler 1 says game focused around FO4 basebuilding.
Spoiler 2 says rust knockoff. Sure; if they do make it basebuilding-centered, this may be a viable take. I mean, it’s still unreliable information and is an opinion from a single person, but hey.
Spoiler 3 is where it goes off the deep end. The first part is okay; it’s just the name and the mention of a location. But then it starts talking about a melee-focused battle royale set in different parts of the world. Which conflicts with the “Vault 76” thing the game is named after, and the earlier information about the location, the fact that it’s Fallout-based, and with everything else. “Rust knockoff” and “basebuilder” are mutually exclusive with “melee battle royale”.
Again, though. I think it’s pointless to form such strong opinions from a basic teaser trailer and contradicting non-reliable leaks.
