Fallout New Vegas' hardcore mode?
That might have it (haven't played hardcore on it yet), but I was thinking of the Ultima Underworlds series ('Rat on a Stick!').
Arx Fatalis was being made by Arcane Studios who wanted it to be the third installment but they couldn't obtain the rights and thus called it Arx Fatalis and developed a few things differently but it matches Ultima Underworld in a lot of things.
I never knew that! It's only $5.99 on gog.com, I'll have to check it out.
