This was one of the first games I played on Elliquiy and is still one of my favorites, so I'm going to try to bring it back. The gist of the game is simple: one person has the power, and has to give dares to the other players to complete. Whoever's brave enough to finish a dare gets the power next and can use it to change something (more on that later), and then gets to decide who gets dares. This being Elliquiy, the dares can (and probably will) run much more towards the sexual side of things.
More details on the rules:
One player begins the game with the Power, but cannot use it for a special ability. The other players must ask the player with the Power to get a dare, and the Power player must give everyone who asks a dare. The dares can be the same, or each person can get their own dare, but everyone must get a dare. Dares can include promises, but those promises are only binding until the Power passes again. Once someone finishes a dare, all other dares are removed, although the new owner of the Power can give the same dares out.
Once you get the Power from finishing a dare, you can do one of three things: change the environment, change yourself, or make a special item.
Changing the environment: The game starts in a large, open warehouse, with a few ceiling lights but nothing else noteworthy. Changing the environment can do just about anything you can think of, from just adding new furniture to the place, to completely changing the location (perhaps we'll end up on a beach, or in a cave...). There are a few limits, however: first, there can't be anything alive or otherwise active aside from the players. There won't be snakes in a jungle (though trees are fine), for instance. Second, the technology level is mundane modern-world stuff. You can have something from ancient times, but nothing futuristic; a laser gun will just make noises and have flashing lights, although the environment could end up like a sci-fi movie set. Note that when you pick this option, you can change any details that were changed or added by a previous player, but you cannot use it to remove special items created by a player.
Change yourself: You can change any physical characteristics of your own character. You can't develop any kind of superhuman abilities, but non-human changes (such as growing extra arms, turning into an elf or catgirl, and so on) are fine.
Create an item: You can create a single item or set of related items with special (potentially magical) abilities. These can do almost anything you want, from candies that make someone shrink or grow, to glasses that let you see through walls, or whatever else you can think of. However, there are a few rules. First, it must be simple to describe; it shouldn't require someone playing out the item as if it were a separate character, and the entirety of what it does should be describable in 3-4 sentences. It should function similarly on everyone, though differences based on the user's gender is allowed, as is differences for how it's used, so long as it can still be fully described in a few sentences. Finally, if the item is supposed to be consumed or otherwise used up, it can only be used six times (so if you make shrinking candy, you only get six pieces of it to give out, and will have to get the Power again to get more). The same applies if the item has permanent or long-lasting effects (such as a belt that permanently changes the wearer's gender, even after being removed). Note that while you need to describe what the item does out of character, the other characters don't necessarily know what it does unless you tell them.
Character sheet: Note that all players begin the game as an ordinary human, with the option of changing by using the Power.
Non-con (Never, Only if asked OOC, Ok, Ok if...):
I'm considering adding these in as extra, optional rules, depending on what people want.
Blind dares: Normally, dares are entirely consensual; the person asking for a dare can decide whether or not to complete the dare, and there's no penalty (beyond not getting the Power) to declining a dare. With this rule, players can ask for a blind dare instead. When a blind dare is asked for, no more dares can be given out (although already-given dares can still be completed), and the person asking for a blind dare is required and compelled to complete the dare. The dare should avoid anything the player listed as "offs" in the character sheet, but beyond that there's no need to ask the character what they're willing to do. Blind dares have two main limits that normal dares don't have: the dare cannot specify how the player uses the Power once they get it and cannot specify how that player gives out dares, and it should be something that can be completed in about 10 minutes (in-character time) or less. Blind dare promises are no more binding than normal dare promises; only until the power passes again.
No identical dares: Whenever the power passes, everyone's dare must be different from any other dare they received since they last had the Power, unless the player asks for a repeated dare from earlier. As always, the player with the Power has final say on which dares are given out, but must still give a dare to each person that asks for one. If the first dare is declined, they still have the option to issue more dares, but only the first dare is required to be different.
Destroying items: A fourth option for the Power is destroying special items made by other players. I'm not sure what kind of limits would be on this power, likely only allowing two or three items to be destroyed, and not allowing you to destroy new items (something like, the last three items made with the power can't be destroyed). This rule is mostly so that we don't end up with a completely crazy game once several items are made with the Power, but I'm still iffy about doing it this way.
Changing others: When using the power, instead of changing yourself, you can change another player. Even if this rule is chosen, you MUST give OOC permission before anyone can use it on you. IC permission isn't required, however. Note that even if we don't have this rule, special items can be used to accomplish similar effects to whoever uses them.
