Yeah. That was just a Very weird choice to just be able to take some stim and suddenly BLOOP! Ghoul!
Add in the insane level of regeneration, which yeah, ghouls could regenerate.. It wasnt regrowing destroyed limbs, and had to be in INSANE amounts of radiation to be able to do it.. Which also made them go feral.
Im.... Curious? to see where they are going with this portraying ghouls as almost completely different from the games. But.. same time.. Meh? Bethsada used up a lot of my good will on starfield.
