There are only 4 questions tagged ethics in 2 years, all by the same user. There is no usage guidance for this tag, and all four questions are about the card game bridge, making the intended scope even more unclear. We have four related tags that are more common and better defined: etiquette, cheating, legal, and perhaps tournament.
It appears that "ethics" has a specific meaning to Bridge players, so as an immediate fix I propose that the existing tag be renamed to
bridge-ethics and given corresponding usage guidance by a user who knows more about bridge. The tag isn't used much yet, but perhaps bridge players will start using it more once it's clearer what it's for.
As other answers have pointed out, there are ethical questions that might belong on this site like the ethics of king-making or of making a game that reinforces stereotypes. If and when such questions get asked in the future, we might consider making a new ethics tag.
(This is more replying to "Is it used properly in the bridge questions?" than to the original question; but it is still an answer rather than a comment)
Bridge has (nearly universal) rules that cover the inevitable mistakes; if you revoke by playing one card when you were obliged to play another there is a two trick penalty, reduced to one if the effect was smaller than usual. These rules, deliberately, do not cover the intention of the player; they are purely mechanical, and questions about them use the
Like most games involving money and international prestige, bridge also has occasional cheating scandals; international pairs have recently used the positioning of their bidding cards to show partner what they hold. This is flagrant contempt for the whole rules system, and questions about it (if on-topic), use the
But there is also a huge area between the two, covering for example how long you are allowed to hesitate before a bid, when you must (and must not) warn the opposition about the unusual meaning of a bid, and what conventions you can play at a particular tournament. These points are covered by "Rules and Ethics" guidance given by the various rulemaking bodies (mostly but not always national), which usually attempts to 'put the players in the same position they would have been in if everybody had played properly'. Since most people believe they played properly to start with and it is impossible for an adjudicator to know what the player intended, this is not easy, and very many of these questions are discussed at all levels in the bridge world. If they are asked here,
ethics is the only reasonable tag.
I think that the ethics tag is just fine but it may or may not be appropriate on the questions it is tagged. As I am not that familiar with bridge I am unable to judge if those tags are used properly or not.
A couple of areas where I think the tag does have some use. Questions about king making in games where a player causes someone else to win/lose while they themselves can't win or the actions prevent them from winning. Another area is co-op games where something may be legal according to the rules but may or may not be against the spirit of the rules.
I don't know if this tag will see a lot of use but I don't see anything wrong with it.
I'm not a bridge player, but I think those questions could all be tagged cheating.
Those four questions appear to all essentially ask whether something is considered cheating in a formal context. If the subject of the question is permissible, it's not cheating, though I suppose it could still be bad etiquette. If it isn't permissible, it's cheating, though it might be a relatively mild form of it.
So the core question is "is this cheating?", and cheating seems appropriate.
I suppose we could consider whether ethics or cheating is a better name for the whole concept. ethics is less loaded, but it's also less specific and not as obvious (only one user has used it?), so I tend to favor cheating.
In the context of board games from the user perspective. The primary arena that really has "ethical" concerns would be publishing. (Is it ethical to report on a publisher that has rejected my game?). That and maybe modern sensitivities (Such as the question of Puerto Rico and the brown colonists cubes). Also the ethics of making a game that reinforces harmful stereotypes. Questions such as Would making The Train1 a fun game instead of an interesting one be ethical? or Should I include slaves in my historic civil war game, or Is it right to make money on a game that causes people harm and others like that.
The thing is I can't imagine many questions with descrete answers appropriate for Stack Exchange, that are also ethical in topic. So yeah in inconsideration with the fact that we have etiquette, cheating, legal, and tournament. I don't see a need for ethics. And based on four questions in two years form one user. It sounds like no one else in the community can come up with a use for them either.
