Role-Play Ideas

Daily Life in Metropolis
A staple of casual role-playing, this RP would focus around a bunch of expats from multiple countries living in a foreign city, and be the story of their lives. What makes this RP type interesting is that it’s pretty much completely open-ended with no goal, allowing you to explore with writing styles and improve RPing without affecting anyone else’s enjoyment.

Under the Same Roof
This idea is an expansion of the Daily Life role-playing, but with a more intimate relations between the roster characters. Essentially, the selected characters live within the same household for various reasons, ranging from host family program, college students that decided to rent a house together, even romantic relations if applicable. The idea is that the intimate relation should be able to brew a lot of interesting interactions that would not otherwise be present in a regular Daily Life roleplay, especially concerning cultural shock and such.

State Visit
Leader A visits Leader B. You know the drill. However, instead of the normal NS formula of go in, talk, leave, a state visit can be so much more. For instance, you can conduct an elaborate opening ceremony, include media interviews and press conferences, take the other leader on a tour of landmarks, describe the lives and struggles of the staffers in charge of planning the visit, etc.

International Military Exercise
A lot of people have been looking for military RPs, and a military exercise/wargame is a way to tell a war story without affecting much. Mock battles, deployments, going into the thought processes of the commanders on the ground, are all potentially interesting plot points to explore. Some diplomacy can be thrown in by having a hostile nation RP spying on the exercise or issue diplomatic protests.

Tourist goes globetrotting
A guy (or a TV crew) go around the world, interacting with local people and seeing sights. They may run into (mis)adventures along the way. This allows for everyone involved to sharpen their storytelling while also creating an opportunity to world-build through exploring various countries.

Attackers on the run
The story starts with a guy planning an attack or a crime of some sorts. After he goes through with it, he finds himself public enemy number one in his country, and the role-play can take on various genres:
Action - The attacker flees from the authorities as they try to hunt him down.
Diplomatic - The attacker manages to escape into a foreign country, requiring the nation’s diplomats to negotiate his extradition.
Legal - The attacker is caught by police and brought to trial before a local judge.
Military - The attacker flees to a lawless part of Anteria, and commandos are dispatched to recapture him and bring him to justice.
Whoddunit - It is revealed that the attacker had help from inside the highest institutions of state. A lowly police detective battles political obstacles as he tries to find the accomplice.
etc.

Election Campaign
Basically, you let other players take control of your political parties and have them role-play the election campaign.

Sports tournament
A tennis cup, or a basketball tournament, or a synchronized swimming competition, the possibilities are endless. You’ll probably want to familiarize yourself with other nations understanding of said sport beforehand though.

Crime Outfit
Characters from various countries can run a crime outfit of various questionable activities in a country of their choosing; from smuggling cigarettes at the docks to gunrunning to trafficking in human beings(!), they have to avoid the police services of the country in question, the difficulty depends on whether the police forces have completely collapsed, highly militarized, or varying in quality.

After the Storm
A major storm destroys the only road out of the isolated hamlet of one of your small towns. Law and order in the village collapses as supplies begin to run out, and everyone is left to fend for themselves. Several people can have characters that try to survive, while the OP would likely control background development, create deux ex machina to advance the plot and roleplay some NPCs.

Plane hijacking
Passengers of a flight from various nationalities are bound together as hijackers take the plane to a country of their choice (controlled by OP/CO-OP), and they have to survive the hijacking in the best shape they can. Difficulty can range from a couple of guys with pistols, to a full on terrorist group. Difficulty can also range in what country they land in, whether the army is actually functioning to abandoned airfields, requiring a Entebbe-style SPEC-OPS raid thing.

Exhibition
The fair is in town! Exhibitions are gatherings meant to educate and teach visitors of the attending states’ cultures and achievements. The RPer can pick and choose what they wish to exhibit, the design and theme of their pavilion, etc.

International Trade Deal
Involves a major global free trade agreement between many nations in Anteria that on paper seeks to lower trade barriers, boost trade and all that “business” talk. It would involve backroom government talks, shady provisions, conspiracy theories and massive opposition in the form of protests and riots.
