Skyrates

Skyrates is a Flash-based MMORPG, set in the world of Skytopia. This world consists of 30 something Skylands which the player fly to and from in search of profit. Although it is a MMORPG, it is unusual in a couple ways. The only way to influence other peoples is economically, depriving them of trade routes and messing up the supply and demand of a specific Skyland. Another difference is the presence of "Sporadic Play" game design. This game design has allows the player to ignore the game at lengths of time, your character following a route that you have planned beforehand. With specific builds of planes, this sporadic play concept can get to almost absurd levels, people having queued up to 1600 hours in a single run.

The game is notable to having a small, if largely involved Fan community. The developers have utilized the fanbase for the creation of a strong Roleplaying aspect of the game, and the fanbase maintains a wiki and forum.

The game is currently free to play on version 2.6, with resets which occur every several months, in theory. The game can be found here.

Tropes used in Skyrates include:

0% Approval Rating: Will happen in the reputation game if you attempt over time, or instantly on the capitals of a specific faction.
Ace Pilot: Your main character, and several NPCs, including Captain Remy Sans-Barbe whose kill count is in the thousands.
Airborne Aircraft Carrier: The Scarlet Blade, Fuseli/Crimson Dawn, Azure Horizon, Great Bounty, Hidden Fleet Platforms and Carriers, Alpha Platforms and Fuel Skylets.
Ambiguous Gender: The Shining One, Grand Artist of the Court of Violets.
- To the point of the devs alternate pronouns every time The Shining One is referred to. One sentence will call The Shining One "he", and the next, "she".
The Artifact: The Court of Violets. With little in common with Skytopia, no shared history and a fairly vague faction concept, they're a fifth wheel when it comes to most storylines. During the Hidden War, the Court's RP Guide was a dev because none of the players wanted to do it.
Berserk Button: Seizing a faction capital is a great way to piss people off.
Black Market: This is where Grog and Catnip is ostensibly sold and purchased.
Color Coded for Your Convenience: Each faction is represented by a different color.
Cool Airship
Cool Boat: The Jade Fan.
Cool Plane
Crew of One: Your character can fly their aircraft all by themselves, even if it's a massive Zeppelin. However, having a crew is highly beneficial. Crews will grant you bonuses in trade and combat, and reduce flight time.
Death Is a Slap on The Wrist: The Pirates which you face know that it would be unprofitable for them to kill you. When you are shot down in Aerial Combat, they simply take a portion of your cargo and allow you to continue on your merry way. (and currently cargo loss in not implemented, making the only negative side effect of losing combat a minor hit to crew morale)
Dieselpunk
Disproportionate Retribution:

"You've been doing pretty well for yourself. Tell you what though, some pirates have been shooting at the tavern. One of them knocked over my drink, and I don't take kindly to that. Why don't you go teach 20 of them a lesson in manners?"

Egopolis: Fuseli, Eltsina, Islo, and Kadath.
Endless Game
Everyone Is Bi: A stereotype of the Court of Violets. Even if not true, new Courtiers do feel some pressure to try and experience everything, so it wouldn't be surprising.
Expy: Several of the planes one can fly look suspiciously similar to actual planes.
G-Rated Drug: Catnip
Global Currency
Hidden Agenda Villain: The Hidden Fleet.
Metagame: Player created tools have been created to allow players to plan their ships and their designs. Also most trade routes can be planned out well in advance for maximizing profit with simple, if prolonged mathematics.
More Dakka: Autocannons
Nice Hat: The Azure League is known for this trope.
Player Versus Player: Averted. The only ways for players to directly influence one another are via economic measures, or the influence game.
Purely Aesthetic Gender: Or Purely Aesthetic Species.
Random Encounters
Randomly Drops: Gunmods
Serious Business: The influence war.
Shout-Out: The games creators have noted that their main influences were the Tale Spin television series and the sporadic play which they found while playing EVE Online.
Sky Pirates: The game's name is a portmanteau of the trope, but despite the name, actual pirating does not occur by the main characters. Played straight with the Random Encounters that one meets during their travels, and the Pirate Faction.
- The fluff makes the players out to be privateers and "sky pirates" though. Very few pirate characters ever show up; those that do either have Plot Armor like Remy, or are either Noble Demon/The Pirates Who Don't Do Anything types.
Status Quo Is God: No matter how many times you run a mission or shoot down NPCs, the enemy never seems to run out of ships, men or equipment.
- Once the Hidden Fleet had taken control of a skyland, it was almost impossible to take it back. Only one or two skylands were ever recaptured, and even then, they fell again.
2-D Space: Ships can move in any direction on 2-D plane, but they is no way to currently ascend or descend.
Unobtainium: Called Unobtainium, it is portrayed as Green Rocks as a trade good, and is also used in roleplay and player discussion as a reason for hard-to-explain occurrences, jokingly or otherwise.
Vehicular Combat
We Buy Anything: Averted - the market is almost exclusively player-driven.
World in the Sky: some two hundred years before the game's setting was the Great War, which resulted in the apocalyptic Great Upheaval that created the skylands and flooded the surface. The gravitational forces holding the skylands aloft are also tearing them apart, requiring the unobtainium derived skystone to maintain stability.
You Must Be This Tall to Enter: To gain access to farther and farther away location, one has to either put on various upgrades, or to purchase new planes with greater range.
