Multi-User Shared Hallucination[+]

Role-playing game (noun), plural: RPGs
Synonum for TRPG or TTRPG.

Note that RPG Research follows the recommend standard of RPG by default referencing tabletop role-playing games unless talking about other formats, or to reference all formats inclusively. 

When referencing multiple formats, to differentiate between formats, RPG Research follows the standards recommended by the RPG Model, to use the 4 formats and their 4-letter acronyms: tabletop = TRPG, live-action = LRPG, electronic = ERPG, and hybrid = HRPG.

We follow the standard established since 1812 that in the use of tabletop games the word tabletop is ONE word not two, so only warrants a single letter in the acronym TRPG.

It is _strongly_ recommended to NOT use the 5-letter acronym TTRPG for tabletop role-playing games, as this is easily confused with Therapeutic Tabletop Role-Playing Games. 

Tabletop Role-Playing Game , the original format of RPG . Often RPG and TRPG are used interchangeably, however the advent of other formats including LARP , CRPG , CYOA , etc. have diluted the term RPG, so TRPG can be used for clarification between different RPG formats.

Other variants include: TTRPG[+] , Pen and Paper RPG, ..., .... 

Role-playing gaming (RPGing) is a cooperative recreational activity with many variants. 

There are two popular definitions of RPG in use today. Since they both try to condense to the smallest practical number of words, some commentary is required.

The first is from CAR-PGa: "improvised, open-ended stories in which the referee sets the stage and the players describe the actions of individual characters seeking a common goal. Playing depends on imagination and group interaction within elaborate rules."

Game publisher Darwin Bromley phrased it even more tersely with: "quantified interactive storytelling."

RPG Research Project founder Hawke Robinson provides lengthier explanations and examples with the following:

Role-playing games are childhood games of "Let's Pretend" or "Cops and Robbers" all grown up and governed with rules. They are very much akin to 

improvisational theatre or "communal storytelling." They are generally a
group activity in which one person -- usually called the Gamemaster --
serves the same function as a play director. He provides the background for
the game, has devised a plot for the players to unravel and plays the role
of any secondary characters the players encounter during their game.
Role-playing games are set against different backgrounds, some real, some
fictitious, in the same way that movies and novels use real fictitious
settings. The number of backgrounds is vast. There are even games where
players can pretend to be animated cartoon characters!
The Gamemaster employs a set of rules that determines all sorts of things,
from how far a player's character can leap to how much of an overheard
conversation in Croatian a character can actually understand. Dice are used
to inject an element of realistic uncertainty, so the players cannot be
completely sure that they will succeed in any given task.

Example

An example by Hawke Robinson illustrates a very basic and quick example of a tabletop role-playing process:

The game referee, sometimes known as the Game Master meets with the players in a comfortable setting around a table, or anywhere they find comfortable, and begins with a description:

“You and your friends have just walked into the courtyard of an ancient building. The courtyard is approximately forty feet square. The walls, built of a tan colored stone material apparently indigenous to the area, are built to the points of the compass. They are about thirty feet high. You entered from an opening in the south wall. You see the north wall has some stairs going up, and the east wall on your right has what appears to be a solid metal door hanging open on rusted hinges. The walls are crumbling in places, and much is overgrown with ivy and weeds. In the center is a large fountain about fifteen feet high in what appears to be the form of a series of three flower-like terraces. Surprisingly, the fountain is currently spouting clear and cool looking water. Looking at the water, your more acutely aware of how dry you mouths are after the long day's hike to arrive here, with no water previously in sight.

The wind is picking up as a storm from the south, with lightning and dark clouds gathering, quickly approaches. It is getting colder by the minute...

What do you do?”

At this point, those playing in the game each take turns telling the GM and the other players what actions they take. Some will have mundane results, others could have surprising consequences. Dice are frequently used to simulate the random events that can occur in life, and make it unknown in advance, even to the narrator, what exactly will happen next. For example, someone may decide to climb the stairs, where there are some loose steps, and depending on how agile the player's made-up “character” is, with a roll of the dice, that character may leap to the top unscathed, or may have a bit of a fall to deal with. Of course, there also could be trouble in the form of “ill-intentioned bandits” lurking within the entrance of the door....

“Because they are cooperative games, RPGs don't have winners or losers in the traditional sense of the terms. In
most games -- board games, card games, and dice games -- there is a clearly defined way to win, and a clearly defined way
to lose, and winning is the goal of the game. In RPGs, the concepts of winning and losing do not exist. The goal as a player
is to "help to create a story and to have fun. You may give your character other goals, but the success of your character does
not determine any sense of winning or losing. Like life, it's not so much whether you win or lose, but how you play the
game" (Stratton, What Is Role-Playing). “
