Man, this is a big game. 150GB.
Went and checked some uninstalled big games on Steam. Doesn't necesarily mean anthing, but:
RDR2 : 120GB
GTAV: 110GB
BG3 EA: 80GB
Witcher 3: 57GB
This is kind of weird, though: Skyrim SE 14GB compared to Fallout 4's 100GB. What's up with that? Sure, it's bigger, but it's not sixteen times the detail or anything.
