I like playing board games. They are a lot of fun. Working out how to use the rules effectively is good, mental exercise.
Not everyone agrees with me. I sometimes run across people who do not particularly care about the rules. A common line from such people to excuse their behaviour is “It’s only a game.”
Try that line on one of their games, and watch the explosion.
Games do have rules. In the interests of peace, if you are playing a game, play by the rules. Do not give someone else a hard time for playing the game correctly. If you really do not want to play the game, then do not play it, but please do not ruin someone else’s game.
