I’m loving starfield and I’ll agree with this. It’s a mid eighties score kind of game. If it’s what you want it’s amazing, but the people calling it game of the century and whatnot are buying their own hype.
On the other hand, it’s likely to have serious staying power as an all time classic game, Bethesda is great at that and there’s a ton of room for people to use it as an incredible mod canvas. I don’t think that should affect launch reviews though.
A new engine would just have to have a new mod API. Plenty of engines have mod APIs. Nothing’s really stopping them, but they really love driving creation engine onward for some reason.
