Concept of Marginal Advantage ---> How to WIN in a game or a competition using MARGINAL ADVANTAGE !!!

While day dreaming, I thought about the concept of Marginal Advantage (on my own - do not remember reading it previously). And then, I Googled it. Found something interesting from the link:


"Despite the fact that these games function in drastically different ways and demand completely different skill sets, the expert players, the players who consistently win, always share a single commonality: they play comfortably with a marginal advantage.

The marginal advantage embodies the notion that one cannot, and should not, try to “win big.” In a competitive setting, the strong player knows that his best opponents are unlikely to make many exploitable mistakes. As a result, the strong player knows that he must be content to play with just the slightest edge, an edge which is the equivalent to the marginal advantage. More importantly, a one-sided match ultimately carries as much weight as an epic struggle. After all, the match results only in a win or a loss; there are no “degrees” of winning. Therefore, at any given point in a game, the player must focus on making decisions that minimize his probability of losing the advantage, rather than on decisions that maximize his probability of gaining a greater advantage. In short, it is much more important to the expert player to not lose than it is to win big. Consequently, a regular winner plays to extend his lead in a very gradual, but very consistent manner.

Amateur players, on the other hand, try risky, greedy strategies. In CounterStrike, for example, it is not unusual for amateurs to dash out into crowds of enemies trying to pull off a miraculous string of headshots in order to eliminate the opposing team. The majority of the time, this kind of amateur is fragged in a nanosecond. Expert Counterstrike players, on the other hand, patiently and carefully pick off enemies, knowing that such caution and precision virtually guarantee a win.

Moreover, amateurs often have no idea what to do with a marginal advantage once they gain one. I have personally watched countless games of StarCraft in which a player gained a massive lead but later lost the game. An opponent moves out a large force, and the amateur annihilates it with ease. At this point, the amateur has a marginal advantage: he has not yet won, but his opponent has lost his military and cannot apply any pressure for some time. The amateur in this situation will immediately try to win by launching a counterattack and will then crumble to a strong defense. Alternatively, the amateur will expand excessively, overextending his bases to the point where his defenses are too thinly spread. Such decisions violate the law of the marginal advantage, as they allow the opponent to get back into the game. They erroneously attempt to extend the lead, as opposed to maintaining it.

So, what’s so special about the marginal advantage? It might seem that all I’ve done is imply that newbie players take unnecessary risks and experts do not. However, just as playing for a marginal advantage is the hallmark of the expert player, the presence of a potential marginal advantage in a game is the hallmark of excellent competitive game design. The Mancala tournament brought this sharply into focus for me. Building in and allowing for a marginal advantage leads to exciting and dynamic play.

Not that providing for a marginal advantage is the only critical element in competitive game design. I will concede that all reasonably designed competitive games share three basic traits: ambiguity of optimal play, diversity of play, and allowance for skill.

First, there is no such thing as a good competitive game that has an obvious optimal strategy. For example, there is no competitive tic-tac-toe gaming, as two logical players would tie every time. I remember playing an old real-time strategy game called KKND, where one of the units was clearly the strongest unit in the game. Playing against my brother degenerated into a fray where we hurled masses of the same unit at each other until one of us got bored and stopped playing. On the other hand, a superior game like StarCraft presents a completely intractable problem. There is no best race, no best strategy, and certainly no best way to win.

Second, a quality competitive game should have a variety of techniques that can be employed in order to win. That is, if a player performs strategy A, the opponent should have more than one reasonable response as an option. Games frequently have a system of built-in counters. Theoretically, game creators insert such counters to avoid the danger of an optimal strategy. However, these kinds of systems often cause games to be nothing more than a fancy multimedia version of rock-paper-scissors: Unit A counters Unit B counters Unit C counters Unit A. On the other hand, excellent competitive games, such as Marvel vs Capcom 2, allow for huge diversity in response. In Marvel vs Capcom 2, players can elect three characters to form a fighting team. With fifty-six characters from which to choose, Marvel vs Capcom 2 offers over 25,000 combinations of possible teams, presenting the player with virtually unlimited options. At the highest level of play, strong competitive players can be seen using drastically different teams and styles.

Third, a good competitive game should test a player’s skills and minimize the element of chance or luck. Ideally, the probability of a weak player defeating a good player should be as close to zero as possible. For example, in a well-designed game like WarCraft 3, it is highly unlikely that an amateur will be able to control his units or respond to his opponent’s tech patterns as well as an experienced player. In fact, the best way to test a player’s skill in a game is to present the player with more decisions. In WarCraft 3, a player not only has to make major decisions, such as which buildings to make or what hero to choose, but also has to make innumerable small decisions, such as how to precisely control each unit or time an attack. By presenting a player with more decisions, the game offers amateurs more opportunities to make mistakes and experts more opportunities to shine.

However, against this framework of competitive game design, we can understand why the marginal advantage gives a game flavor and excitement for both the player and observer. The marginal advantage not only provides the player with the joy of overcoming obstacles, of finding new and more effective methods of winning, but also allows a player to express himself, to have his own unique style. By exploiting the marginal advantage, the expert player is both a problem solver and an artist. In WarCraft 3, StarCraft, Marvel vs Capcom2, and CounterStrike alike, we see the individuality of the players shine through: some play aggressively, some play defensively; some are renowned for their solid, steady play, others for their unorthodox tactics.

We respect the brilliance of their expert skills; we admire their ability to win. Yet, at the same time, we appreciate the aesthetic of each player’s technique, that each player finds a solution that is so different from the next player. If too many decisions are clear cut, the player has no need to discover his own marginal advantage over the field, and the competitive game collapses into redundant, unexciting play, unappealing to master and unappealing to watch.

The brilliance of a competitive game is that the designer must limit his role to be the creator and balancer, to allow for the potential of innovation. In this way, each player can uncover his own marginal advantage and become the true pioneer of the game."

I guess concepts from here can be applied (and ARE applied, whether we realize it or not) in Business successfully :))).

(P.S: I shall try to edit this article some time later. Feeling a bit lazy, right now :)
