This is seen more in games of sports or highly competitive environments. As someone who has done club volleyball and basketball, some of my teammates were entirely affected by one bad game they had and the reaction of their fellow teammates or coaches. A bad experience can cause a player to stop liking the game ad sometimes cause them to not want to play the sport and game anymore.

Especially with a close group of friends or family, the way we act while playing a game is changed. Games always come with rule-bending or disagreements and how 'much' we care is affected by who we are with as explained in the sentence before the highlighted.

I have also noticed in many people close to me, including myself, that attention spans are the smallest they have ever been. No one is attentive anymore because no one wants to converse face-to-face. They would rather text each other. Although technology can create the illusion of hyperconnectivity, the contrast happens due to its inevitable negative effects that outweigh the connectivity.
