Even though my PhD-research has focused exclusively on Second Life, I will in one of my theoretical chapters examine the concept and evolution of Virtual Worlds in general. As a prelude to a discussion of several Virtual World definitions and typologies, I have chosen to look closer at what two prominent figures within the field have to say about Virtual Worlds. Richard A. Bartle (co-creator of MUD1, which by many is considered the first computer-based (albeit text only) Virtual World) and Cory Ondrejka (co-creator of Second Life) both agree that Virtual Worlds are not games. However, what’s interesting is that Bartle and Ondrejka seem to reach this conclusion based on very different arguments.
On the first page in his book, “Designing Virtual Worlds”, Richard A. Bartle proposes a definition of Virtual Worlds:
Virtual worlds are implemented by a computer (or networks of computers) that simulates an environment. Some – but not all – entities in this environment act under the direct control of individual people. Because several such people can affect the same environment simultaneously, the world is said to be shared or multi-user. The environment continues to exist and develop internally (at least to some degree) even when there are no people interacting with it; this means it is persistent. (Bartle, 2004, p.1)
According to Bartle Virtual Worlds began as computer games, which explains why much of the vocabulary used to describe Virtual Worlds is games-based:
Thus, the human beings who interact with the simulated environment are known as players rather than users; the means by which the environment introduces goals for the players is called gameplay; the activity of interacting with the environment is referred to as playing. (Bartle, 2004, p.2 – original emphasis)
Further, Bartle explains that the first Virtual Worlds were text-based and known as Multi-User Dungeons, MUDs, and although “all these persistent, shared, computer-based environments can and should be referred to as MUDs, the term is sufficiently loaded that outside the cognoscenti it is unlikely to be universally interpreted this way”, and Bartle therefore prefers to adopt the “more descriptive and less emotive” concept of Virtual Worlds (ibid. p.3). Based on Bartle’s initial characteristics of Virtual Worlds, which in the first chapter includes a review of what easily could be perceived of as computer-game history, it is interesting to see why Bartle dismisses the term “game”. Bartle, in fact, devotes the book’s sixth chapter entitled “It’s Not a Game, It’s a …” to explaining why he has abandoned the term. The beginning of the chapter reveals the core argument:
Virtual worlds began as games. However, right from the beginning – MUD1 – it was clear there was more to them than being mere games. Trying to convince people to take what they considered to be a “game” seriously was problematical, though. In academic circles, the only intellectual acceptable games were traditional ones, such as chess and checkers. A new game was not a worthwhile object of study. Playing games was a waste of computer resources. Thus, virtual worlds became “simulations” – and far more respectable! (Bartle, 2004, p. 473)
Bartle’s need to distance himself from the game term was essentially due to a public (mis)conception of games as unserious contexts/activities and hence unworthy of serious studies. While this concern is commonly recognized and shared among several authors, it does come across as somewhat curious insofar as Bartle insists on using a gaming vocabulary and gaming principles when discussing design of Virtual Worlds.
Nonetheless, the need to differentiate between games and Virtual Worlds is also of concern for Cory Ondrejka, although his argumentation is quite different from Bartle’s. According to Ondrejka Virtual Worlds represent a new category of digital experience different from games most notably because Virtual Worlds like Second Life have no game fictions or leveling;
Strong game fictions mean the games take place within relatively cohesive settings that discourage intermingling with the real world. Fantasy motifs are common, but certainly not the only option. Leveling is the process of measuring progress via increases in experience points. These experience points are gained by activities appropriate to the level, and each new level grants the player access to new abilities or game features. (Ondrejka, 2008, p. 230-231)
While fully recognizing the close relationship to games due to shared history, technology, vocabulary, and oftentimes customers, Ondrejka continues to delineate the difference:
Virtual worlds are something different. While still massively multiplayer, meaning that thousands of players simultaneously experience the world in a shared space, they possess neither strong fictions nor leveling. Instead, their defining characteristic is the ability of residents to generate creations of value within a shared, simulated, 3D space. Strong, predefined fictions are not appropriate, as they limit the design space available to the residents. Instead, residents create their own fictions and communities, imbuing them with meaning through interaction. (Ondrejka, 2008, p. 231)
For me, as seen from an educational design perspective, the lack of gameplay (i.e. pre-determined context, goals of use, roles and rules of interaction, progression, and quantifiable outcome) is one of the most important – if not the most important – defining features of Virtual Worlds because of the design possibilities and challenges it poses. “Your World, Your Imagination” truly has defined my SL experience since 2007, and I have to agree that it’s not a game! Still, exactly what it is remains to be determined ;-)
 Ironically, as Bartle further notices, when Virtual Worlds became commercially successful through the advent of Massively Multi-Player Online Role-playing Games (MMORPGs), such as Ultima Online in the late 1990’s, Virtual Worlds were once again commonly referred to as games. Nonetheless, the less serious connotations related to the term game continued and in Academia, the concept of “serious games” emerged to justify the study of human behaviour in games used for purposes other than mere entertainment. The term “serious game” was actually used long before the introduction of computer and electronic devices into entertainment. Clark Abt discussed the idea and used the term in his 1970 book Serious Games, although his references were primarily to the use of board and card games.
 Based on Salen and Zimmerman (2003) Ondrejka defines a game as “a system in which players engage in an artificial conflict, defined by rules, that results in a quantifiable outcome” (Ondrejka, 2008, p. 231).
