Mindark say 'all trades are final' but as a community I don't think we should sink to that level.
OK there are individuals in here who would callously take advantage of a guy's unlucky or careless mistake but be it on their own conscience rather than letting them cop out by reiterating some convenient small-print disclaimer.
As a community I think we all should try to set an example by choosing to take the fair and just action in these circumstances (ie. contact the seller and return the deeds or whatever items are involved).
I think this is a very valid way of looking at these situations. I would wager that many folks who consider Entropia to be a non-game would adopt this view. If EU is seen as a dimension of the real world, in-world morals are likely to be adopted quite directly from real world morals.
The folks who view Entropia as a game may or may not agree. There are many possible goals in the game. Some colonists chase only skills. Some strive to profit. Some are here for the 3-D chat capabilities. Some players are keenly aware that EU is a competitive game. Some don't care so much. Depending on one's goal(s) in the game, their current bank roll/skills, their strategy, their perceived reputation, etc., it could be viewed as a GAME PLAY MISTAKE to abstain from capitalizing on a good deal such as this. It may be morally wrong, neutral, or right, in that person's conscience; I would not claim to know which, but if the trade is NOT morally wrong, it could very easily be pragmatically wrong to reverse such a trade (or abstain from accepting the offer in the first place), in the same way that shooting the air is a pragmatically wrong way to play eco.
We generally play games to the best of our abilities, within the rules. There is no set way to win EU, but there are ways to achieve our personally set goals that may be more effective than other ways. I can't help feeling that the way some folks go off on certain rule-abiding activities, such as pirating, is parallel to walking into a Monopoly tournament and going off on an opponent who gains an advantage over others by bidding on a property that you declined to purchase; your justification of course being that your friends don't play the game that way.
Make no mistake, there are most certainly in world morals. Borrowing an items from someone with the agreement to return it, and then refusing to do so, may not get MindArk pounding on your door due to All Trades Are Final (ATAF), but one would have to work hard to convince me that such lying is mere role play. On the other hand, most actions performed outside of the chat window, such as shooting a person in the Twin ring, ARE role play, and do not necessarily reflect real world morals.
I think it is more difficult to discuss these situations than people believe. Even assuming all folks gladly obey their own conscience, the morality of a lot of these major issues seems, to me, to draw back to how people perceive the world of Entropia.
