Really? I find myself constantly reaching the cap of my inventory despite there hardly being any dungeons (gotta stay on topic :celebration: ) but thats because I basically loot EVERY piece of ammo (which, since I play hardcoe mode, has weight) and weapons so I can sell them later, which I forget about 90% of the time
The Vaults is the dungeons of FNV. Theres five Vaults in the game, with one being for show only.
The biggest Vault has like five floors.
Though I think Fallout 1 and 2 had the best dungeons. I still remember the Glow, which Vault 34 quite resembles. Or the Sierra Army Depot in Fallout 2. Sprawling, underground prewar bases holding sinister secrets of the old world, with you being the first to breach their defenses, was a feeling i was missing from FNV.
