When I play board games, I tend to use a pretty consistent strategy. Basically, I will stay extremely loyal in any alliances I may form, but when someone wrongs me I will dedicate myself to destroying them. The grim strategy, more or less. Since I tend to play with the same groups of people, the idea is to build up a reputation that will serve me well in future games. I am willing to act irrationally within one game to help my chances in later games. I can’t honestly say it’s worked out all that well for me, but I consider it to be a reasonable strategy and its effectiveness is besides the point.
Most people are fine with it, but on a couple occasions people have objected to it. Basically, they say that it is unfair. When people sit down to play a game, they should set their goal as winning that game. Having a player who acts irrationally within the context of that game spoils it for everyone else. Usually, this objection comes after they have been the target of one of my grims, despite my having explicitly told them what I would do. I would argue that when playing a game the players are always judging the actions of other players based on previous encounters. That is an inescapable part of the game and therefor building a useful reputation is no different from getting better in any other way.
My question to all of you is twofold. First, is my strategy unfair? Is it part of the implied rules when playing a game that each player will treat the contest independently? I use board games to lay out the question, but it could be readily expanded for other less obvious contests. Secondly, on a more personal level, would you be less inclined to play with a player using this strategy? I’ve been considering dropping it because it seems to annoy some people.
