A brief history of cooperation in multiplayer games

Most early video games, of course, were multiplayer games. Games like Spacewar, Pong and Gunfight, however, were also simple one-on-one games in the tradition of classical board games such as chess. At the formal level, at least, such games do not inspire cooperation since one player’s gain is the other player’s loss.

Following the simplistic and competitive successes of Pong later games introduced the possibility of cooperative play. Two schools of thought competed for quarters and screen time. In games of the 1980s like Joust (Williams, 1982), Double Dragon (Taito, 1987) players could join forces against the enemy hordes but were also likely to be unstable allies as players were able to directly hurt one another (Double Dragon even ultimately employed last man standing scoring conditions. as players would fight each other for the glory of actually winning the game). Eliminating much potential for inter-player conflict Gauntlet (Atari, 1985) and its descendants cast players in complementary roles that needed to be handled appropriately for the group to succeed.

Such experiments were obviously predecessors of the team-based Counter-Strike and are evident in many other highly popular online PC games such as Return to Castle Wolfenstein (Gray Matter Interactive Studios, Inc., 2001) and Battlefield 1942 (Digital Illusions CE AB, 2002).

In terms of gameplay (disregarding for now the broader social context in which the game exists) those games all invite social tension albeit on a modest scale. In the case of in-game resources (health potions in Gauntlet, special weapons in Double Dragon) each player may be tempted to simply gobble up as many goodies as possible. And the Battlefield 1942 player may feel the urge to indulge in personal military heroics (such as semi-suicidal air-raids) without bothering with the carefully pondered strategies of her team. This tension, however, may clearly be part of the appeal and cannot feasibly be countered without seriously jeopardizing the enjoyable player freedom offered and enthusiastically flaunted by the game worlds in question.

A remarkably different approach to game design was displayed in 1978 when Rob Trubshaw and Richard Bartle wrote the lines of code that was MUD. The system drew inspiration from earlier adventure games as well as pen-and-paper role-playing but what should interest us here is the fact that MUD was, in effect if not by intent, an experiment with social dynamics in game worlds.

Being multiplayer at heart, MUD was a virtual world in which players pursued individual goals but also shared the responsibility of keeping the world useful and enjoyable. Thus, the cooperation required by the players here is analogous to the joined effort that must be undertaken by members of real-life societies. In an important sense, then, the task of the game world designer is comparable to that of the political philosopher, attempting to describe institutions that ensure the desired levels of freedom, fairness and happiness. Experienced virtual world designer, Raph Koster, who co-manages Sony’s MMORPG Star Wars Galaxies acknowledges this:

‘I think anyone who doesn’t think that MMOs are social experiments hasn’t tried
running one yet. It’s not that you set out to create a social experiment-we don’t have test plans for our subjects, formal hypotheses to prove, or anything like that. You set out to make a game, and quickly discover that you’re suddenly a politician running a game the size of a city. You’re suddenly a social architect worrying about issues you never had a clue about.’ (quoted in Pika, 2004)

Although designers of pioneer virtual worlds such as Habitat were specific about the difficulties of reconciling the preferences of various player types (Morningstar & Farmer, 2003) many subsequent systems apparently did not fully anticipate the potential tensions between users/players. Famously, Ultima Online, in its initial incarnation, did very little to discourage anti-social behaviour among its citizens. Thus, the game world soon became rampant with grief play, a term now used to cover various types of deliberately anti-social behaviour (see discussion in Foo & Koivisto, 2004). Particularly the number of players who enjoyed preying on other players reached levels where other types of play (i.e. advancing through the game’s craft system) became hard to enjoy (Kim, 1998) as the game world began to resemble ‘Afghanistan after the Soviets left‘ (Rollings & Adams, 2003 527). The mounting in-game tension was attributed to the game’s design. In this spirit it was decided to graphically single out player-killers and to designate certain areas of the game world as safe. Thus, player-killers would be marked by a red aura and it was no longer possible to die at the hand of another player in Ultima’s urban areas. It other words, while Ultima Online did not eliminate player-killing on the code level (as many of its successors have done) the game had raised the stakes involved in blatantly anti-social behaviour, which was soon notably diminished.

Killing another player character in Ultima Online, of course, is arguably not against the spirit of the game. In a medieval world populated by monsters and assassins the case can obviously be made that killing is actually in-character, i.e. consistent with the role one has chosen to play. Such arguments fare more poorly when it comes to technical cheats. A pervasive problem in online gaming has been the creativity put to use by some players in order to exploit bugs in the games or to gain various advantages by tinkering with the game code. A measure of the problem can be gained by the proclamation by game developers Blizzard in September 2003 that they would shut down 400.000 user accounts at their game portal Battle.net. These accounts had been associated with ‘a hack or a cheat program‘ and were eliminated to ensure that the portal would remain ‘a fun and safe place to play Blizzard games’ (Battle.net, 2003).

If games were all about conflict, grief play and technical cheats would not receive such intense attention and would not give game designers sleepless nights as they attempt to foresee the next counter-move by ingenious (if immoral) players. Notably, no developer sleep is lost over the intentional conflict manifest in the aggressions of Tekken players or the drive towards mutual destruction in real-time-strategy games. Such discord is intentional and entertaining while social dilemmas emerging from human interaction are often not.

Progress cannot be stopped


Yes, Ballgame.exe lovers everywhere, the rumours were true. Here’s the new improved version, with flashy graphics, hillarious effects and a staggering 3 megabyte – but remember fans, deep down it’s still the same good old ballgame.exe that we all love so much.

Oh, and there’s a bug (or is it a feature). Evil Blue Ball and Yummy Apple may at certain times leave the game space entirely even though they are both “solid” and set to bounce off the gamespace border. Any one who can see through this problem (don’t exploit it now!) has earned him- or herself a beer in the student bar.

News.com on griefing

[Via Gonzalo]

Cnet News have a new piece on griefing. It reports that “Now an increasing number of companies are fighting back, using a combination of technology, sociology and psychology to limit griefer damage.”

Now, I think it makes sense to consider many aspects of grief play directly detrimental to the game atmosphere. But I don’t agree with the apparent assumption that behaviour that does not live up to the “social contract” must be eliminated at all cost. Nor do I find it a sensible solution to entirely do away with possibilities for dramatic player-player interaction – “because then people can’t hurt each other”. The interesting game design challenge is to keep the drama and excitement intact while diminishing the effects of grief play. A few players should not be able to wreck the game space if they choose the dark side, but I’m not sure they should not be able to upset it.

Some reflections of The Package Game

At Danish Christmas get-togethers the package game is often played. Here are some reflections based on recent personal experience. Disclaimer: None of this is to say that my family does not consist of genuinely altruistic warm-hearted Christmas-spirited über-philanthropists.

Rules: Each player brings a package (of some pre-arranged monetary value, say $3) which is placed in a package pool of un-owned packages. In the game’�s first phase players take turns rolling a dice, each 6 rolled enables the player to take one package from the pool. When the pool is empty the game shifts to phase two in which a 6 lets a player take any package owned by another player. Usually, one person sets an alarm clock to a setting within a certain announced interval (e.g. 15-25 minutes). When the alarm sounds, the game is over and everybody keeps his or her then-current presents.

Of course, if the clock-setter is also a player, this creates a slight unbalance as one player is privy to special information about the game state.

So, what can we say about the game dynamics etc.

  • Technically, this is a zero-sum game. The sum is fixed (number of packages).
  • There are (technically) incentives to cooperate. For instance, in a player group of 10, 5 might agree never to ‘steal’ from one another. Unless the rest catch on, anyone on the ally side will then only be potentially victimized by 5 players, while any non-ally will have 9 enemies.
    Less than full-blown pre-game conspiracy will do. In the logic of Tit-for-Tat any player may (at a short-term cost) communicate his or her vengefulness by always reciprocating an attack � the message may be clearest if the person consistently steals the present that the other player stole from him or her most recently. However, this strategy works poorly against itself and the trick is of course when to quit if caught up in a disastrous series of mutual retaliation (hey, I take my package game seriously).
  • The game has negative feedback (there’s a push towards an equality equilibrium) due to the norm (see below) that you should generally steal packages from those who have many.

A number of social norms seem to apply in the games I’ve participated in:

  • You don’t steal packages from small children (unless they have huge numbers of packages)
  • You should not steal packages from the very package-poor (players generally scan the table for the larger piles and steal from them)
  • ‘You don’t steal from extremely close family (your own children, your spouse). Alternative phrasing: You don’t steal from those with whom you will be next to you on the car ride home. Alternative 2: You consider packages taken by members of your household as partly yours since they’ll be under your roof (i.e. the value of taking such a package is less than 1 since you’re partly stealing from yourself).
