Lets say you wrote a really cool game that is a online MMORPG. In the game, which you do not know , there is a bug in your programming that allow players to have a unfair advantage ( e.g. get free money for nothing ) over other players who play the game fairly. You dont know about it this bug, so as a game rule with all the players who use your online game, you tell all your players that they can not take advantage of your software bugs if they find them. Now in my opinion, that just means your game was not thoroughly tested to find all these bugs. Maybe your beta testers are not spending enough time to find these bugs that players in the game can find. I dont know. Is this a sign of sloppy software development? Thats the question ..... A long time ago, I used to play a online game called Runescape by Jagex , and in their game rules with their players , they have this exact rule that, if you find a bug in their software that, "Players must not use or attempt to use any cheats or errors which they may find in our software." They still have this in their rules. Even if it seems like a fair rule, how many players do you think in their right mind are going to follow it, if they cant get caught by moderator, because its a bug in the game that has not been corrected? Look at this, from Runescape's website : Scroll down to the section titled : Knowingly Exploiting A Bug https://www.runescape.com/game-guide/rules What do you think, would you make the same game rule with your online players of your game?
