Ok. The thread title states a "Wasteland Carnivale" but this is more of a Wasteland Entertainment thread in general.
The movie "A Boy and His Dog" had a small "theater" which was basically chairs and couches under a shade with an average Tube TV in front playing different cuts of some old movie clips catergorized to sections that contained action, nudity... They served popcorn and played the same reel the next day in exchange for any canned good (which was the film's main currency).
The Metro series had raiders watching rats run across a sewer and betting on who gets to the finish line first. In the second game they even had a theater with several acts.
FO2 had New Reno where you could watch a boxing match and join yourself. You could also watch a considerably long monologue by a stand up comedian and his jokes were pretty rad (pun intended).
New Vegas had well...New Vegas. The Strip was pretty much what you'd expect (maybe a little toned down.) The most entertaining part was a random encounter with NCR ladies dancing in the Ultra Luxe fountain. They did OK for the Aces Theater acts, the fact that they dedicated a whole quest for it. The acts that followed were average. Hadrian the Ghoul's act was pretty disappointing but it was more due to the voice actor's delivery of the lines. BUT we were also fortunate enough to have had The Thorn (though the enemies froze up occasionally forcing you to reload an earlier save.)
FO3 had the short encounter with The AntAgonizer and the Mechanist and unfortunately it was one you had to stop. Since they were going for a downright miserable experience with the game, it didn't really need entertainment anyway.
Now this is pretty ambitious but for FO4 I'd like to see a Carnival. Nothing too big have few tents with booths in between
Maybe have your typical Clown, Acrobats who can teach some melee moves, Deathclaw Tamer (Admit it, you wanna see Red Lucy back *wink *wink), possibly have a good Super Mutant for a strongman...
You can even have a "Grandson of Bob's Iguana Sweets" outside with kids lining up.
For the quest, I would love to see a Carnival Murder done in the post-apocalyptic setting. This is where they could really get creative with possible scenarios ranging from someone simply getting clubbed over the head, to poisoned food to something extreme like finding a limb in one of the animal cages.
Opinions?
