So I guess it makes sense that instead of having New Reno be a boring "dirty grey and brown town of dirty degenerate gamblers", they added some non serious stuff to give it a 1930s Chicago feel. And instead of having San Francisco be a "dirty grey and brown town of dirty Asians (who act like everybody else)" they introduced a bunch of corny ancient Asian historical stuff.
It depends on your tolerance. Some people will laugh at Pinky and the Brain references, Monty Python references, shit bombs, shotgun weddings, getting a sex perk to screw the bosses wife, talking plants that play chess, kungfu gangs, scientology and Tom Cruise, porn studios, porn collecting games, etc. Just like some people might like an anime or JRPG Fallout, or some people might think of Fallout 3 being superior to Fallout 1. Tastes vary. But Fallout 1 wasn't a gimmicky lulz fest, and for those of us that didn't want the game to be turned into a stupid joke, Fallout 2 was a mess.
It still annoyed me, but I think that if they took out all the non serious / corny elements (including those ridiculous super mutants) there wouldn't be that much to do in post apocalyptic storyfag RPG, keeping in mind the rules of political correctness they had to work under.
And as for why porn studios are stupid...do you guys really need it spelled out to you? It's supposed to be post-apocalyptic but people are buying DVD's to watch in their home theater or going to XXX movie theaters? Why not include TV shows while you're at it, or famous actors (oh, they already did).
New Reno is stupid because it's both the largest city and it's a port town without a government. If it was an out of the way place like the Den it'd make sense, but it's like having a country that consists of farms and Las Vegas. The other stupid thing is that the gangs that run the place aren't wasteland gangs, they're Scorsese rejects.
As for the other locations:
The first town (Klamath?) is pretty much nothing. I was confused when I first got there because there's nothing there. Oh, and I think there's some dungeon with trash mobs.
The Den is supposed to be a government-less town, but it's hard to tell because the only other town you've been to so far didn't have a government either. Nothing memorable. Well, it has a ghost.
That lulz fest farm place. Shit bombs. Shotgun marriages. Pink and the brain references. Not much else.
Vault City. Actually a decent location, though it's a bit stupid you can help the NCR spy on them and help them catch the NCR spy at the same time.
Ghoul town. Harold was annoying. Really didn't need to see him again.
New Reno. See above. Plus, you can work for all four gangs at the same time and they don't care.
Redding. It has a dungeon where you kill trash mobs. Don't remember much else.
That human/mutant place. Liked the idea of human terrorists trying to kill mutants, and it actually let's you pick sides. The chess playing plant was more looney toons stupidity, and it was kind of stupid that the sheriff drops what he's doing to join you, but it's a decent location.
NCR. Supposed to be the capital of a great nation and it's a city sitting in the middle of nowhere (I know it's supposed to be the northern edge). Oh, and that girl from the first game is running things.
Vault 13. Friendly talking Deathclaws.
San Francisco. Kung Fu games and Tom Cruise jokes.
Didn't get to the Oil Rig (didn't feel like fighting through the tanker).
For me at least, only Vault City and that human/mutant place were the only interesting locations in the game. The rest felt either bland (Redding, the Den) or were just annoying and stupid (SanFran, New Reno). Even the better locations had some stupidity though (like the plant/scorpion chess game).
