Almost everything that is in computer games is brought there from life. Thought, and what of the games we took in the real?
Here I am, for example, sometimes overtaking a person in front of me using a “strafe” is a technique of movement from games like Quake. Movement to the side, not a turn, no, but I go forward and shuffle a little in the side. He began to notice such a thing after several days spent playing. I have not indulged with a quake for a long time, but sometimes I continue to walk like this - it is convenient.
