Let me answer the OP's question directly. The gun you see on your screen in a game is not a gun, the meaning is vacant. Instead the shape of a gun is imbued with the essence of an outlet for our inhumanity.
It is the purpose of an object that defines its meaning not the reverse. A gun is stubbornly purposed to destroy, however this property is not unique: Nuclear ordinance, tanks, missiles, canon, musket, sword, crossbow, spade, bow, knife, rock. All different shapes of meaning for one unified purpose, the essence of gun.
It is simple to see that a gun shape in a game does not come from the same stock as the previous list. Though the repercussions of having a psychology which demands a simulacrum for this purpose may be unclear it should be blindingly obvious that the purpose of today's games are rooted in the stock of play and recreation; not violence and destruction.
