I did a playthrough with hardcore mode, I remember it more for the fact that you couldn’t spam stimpacks in combat than I do the eating/drinking/sleeping aspect about it. Whenever I play these games I’m always obsessed with conserving my items, so I use the beds to get full health anyways. My son had a mod which let him drink from a canteen with infinite water automatically whenever he got thirsty (the little cheater!).
FO3 had a ghoul follower you could get in the Museum of History (main ghoul city). I actually liked him, he wasn’t whiny and had a nasty shotgun.
Contrast this to some of the New Vegas followers, where Boone always steals my ranged kills and Arcade Gannon is a whiny little wimp (I used him as my test dummy in that game).
“Arcade Gannon”
He’s gay. So true to life ;)
Oh, I remember him. Tough as nails and NO NONSENSE.
