Do you enjoy being “mean” in games?
I find that this totally depends on the group I'm with, but I've observed that people tend to lean towards either one of two sides: those who get a lot of enjoyment from messing up other players' turns and being ruthless, and those who do everything in their power to minimize the impact of their choices and keep the peace.
Some examples: Focusing on blocking progression, stealing resources, forming alliances just to turn on them later, etc. All technically part of a strategy (and potentially a lot of fun), but considered mean by some. On the nice side, it could be evenly distributing resources, taking a neutral option instead of one that negatively affects others, and working collaboratively until you're forced to be competitive.
Are you a "mean" player, a "nice" player, or somewhere in the middle? What are the meanest games you've played?
