Yeah, that is - if anything - a beauty.

^Love this.

Quoted from Mfsrc791:

I think the game risk would make a fun pin. Conquering the world and having battles with other countries sounds fun. Multiple ways to play the game too and you get to chose your starting country.

Quoted from lpeters82:

Not much has changed from my list over the last few years:
King Arthur
So much open source material: Excalibur, Lady of the Lake, Merlin, Knights of the Round Table, Dragons, Holy Grail, Castles, etc.
Monty Python and the Holy Grail
Very similar to the above, but more of a gag.
Zombieland
Campy zombies with Kill of the Week, Woodie Harrelson, Bill Murray, Emma Stone, etc.
Western or Dark Tower
I'm not a crazy fan of Steven King, but I like the imagery from these books. Basically a sci-fi western. I also really like the idea of playing a bandit and using your score to represent your bounty. Basically you are playing as the villain.
Scooby Doo
I think it has appeal with adults and kids. Something with fun interactive monster toys like Monster Bash.
Star Wars
Would love to see something epic, a la Lord of the Rings.
The Matrix
Man vs Machine, plus I really want to have an out of control Sentinel attack multiball.
Steam Punk / Alternative History
I think something with Nikola Tesla could be pretty damn cool.
Fables / Brothers Grimm
A mashup of the open source fairy tails.
Pandemic
Battle to save the world from disease outbreaks.
King of Tokyo
This would be my choice for your "giant beats" theme. It's a bit more colorful then what I think of with Godzilla or King Kong.

Quoted from GotAQuestion:

Edit: And while I agree with CrazyLevi, movies are overdone and I would LOVE to see more original themes, I still have to be honest. Coming up is ... a movie theme!
Every time this thread comes up I'm gonna parrot my favorite response.
Harry Potter
Potential features include:
Moving ramps resembling the magic staircases from the movie.
Vanishing/levitating ball (already been done before but it's magic and I don't think the trick is played out).
Pick a wizard house on plunge. Each of the 4 houses has unique mode bonuses or multipliers for the ball (similar to GoT I guess).
Complete a house and complete a shot back to the shooter lane to choose a new house. Each house requires X number of modes to complete, perhaps leading to a mini-wizard mode.
Tons of options for modes they could choose from. Could base them on classes or events in the book. If based on classes potions requires collecting items and shooting a scoop, flying class requires alternating ramps leading to a final shot, maybe even a jump shot through a hoop. Defense against the dark arts requires bashing standup targets (but on the sides, not like the trolls from MM or the monsters in TH). Otherwise you could use major events like fighting the troll, escaping to hogsmeade, flying the flying car, meeting Aragog, escaping a dementor. The books have almost limitless events to draw from.
Could have 4 mini-wizard modes each with 3 phases - recover the sorcerer's stone, kill the basilisk, win the triwizard tournament, destroy the horcruxes.
Final Wizard Mode - Fight Voldemort
These are just a few things I've brainstormed that they could fill a game up with. I'd really love to see JJP take this on as a widebody. I know it's against the grain to admit this on pinside, especially considering the current leak, but this is a game I'd pre-order a CE of from JJP, sight unseen. There's no other game I'd take on such a risk for but this is a theme I want badly.

Quoted from flynnsbit:

You forgot the Price Police and Thread Derail multi-ball.
I would love to see a Fifth Element Pinball. Good call outs, ZF-1 mode, Collect the 4 stones, Save the world wizard mode. Diva Multi-ball Battle...
Looks like this idea was already discussed: https://pinside.com/pinball/forum/topic/fifth-element-pinball-machine

Quoted from LTG:

Pulp Fiction. Godfather. Zombieland.
But to condense things. Maybe combine them in one winning title. Pulp Father Land.
