Social viewpoint:

Mr. Yang said that he started to play script killing because of social needs. "You can meet new friends through games. Script killing is friendly to novice players, and players will not be eliminated before the game is over. The sense of participation has always been there, which can ensure that the player group continues to expand. "

The online game experience is not favored by some players and offline stores. "Shops with limited quality of real life will affect players' sense of substitution, not to mention online games that rely solely on reasoning." Teacher Yang thinks that the online form can't bring the environment and communication that the script killer needs, but the script killer needs the actual venue.
