Bah. Ridiculous cults and shit harks back to Wasteland 1988. You guys are mad that this isn't down to earth and sensible enough? Fuck you.
I'd put it this way: there's goofy, and then there's dumb.
Goofy is straightforward, easy to grasp, and fun. Usually, it's set-up or just plain window dressing. Dumb is giving your player an in-depth, plot-based problem to solve and presenting a solution that's tortuous, unclear, or just plain dissatisfying. (Sure, I haven't played W3. Maybe they'll make something great out of this.)
Goofy sets the tone. Dumb veers wildly.
Goofy is 'you're being attacked by an 80s robot called Turbo Cybertrike'. Dumb is 'in this version of Fallout, it turns out there are mass-produced humanoid robots for some reason and they want to be free and they're being attacked by humans because, you know, Blade Runner, I guess, isn't this series all about the homages? Anyway, pick a side.'
Goofy is 'a tribal village that basically worships the PC from the last game'. Dumb is 'OK, so one of these tribals has one arm...and you get the other one to dramatically cut off his own arm...it's a symbolic gesture, I guess, but then they all get on a train together and the quest ends.'
Goofy is 'these monks worship the atomic blast and suicide-bomb themselves in honour of it'. Dumb is 'you betray them all and then the monks' wise old leader uses his dying words to say "You suck!".'
Goofy is 'a Stephen King hotel filled with murderous, crazy caretakers'. Dumb is 'a Stephen King hotel that's filled with murderous caretakers, because you see, all along it turned out that *insert complicated explanation about ghost-powered belief systems or hallucinatory fungus or dimensional portals that actually just comes down to 'they're crazy'*'
Goofy is...whatever, you get the point. I don't think that's just semantics.
