10 minutes? 15? It's 3 floors deep.
It's not too long objectively speaking. Subjectively...
But yeah, one thing that really pissed me off in 1 was how those green/red rings under NPCs identifying them as friendlies or hostiles was restricted to a perk. Perks in 1 and 2 take forever to get and you can only get so few, and when Ian/Katja/Dogmeat uses the same character model as everyone else it should not be optional. Thank god 2 made it standard.
