around the year 2000, a friend of mine from school got banned from many large Half-Life servers because they claimed he was cheating. He was not, he was just that good. I swear even if you watched him playing you could have sworn he used an aim bot. The crosshair was almost permanently stuck to the other players' heads. But that's just how good he was. Shame that E-Sports wasn't a thing back then, he could have earned a fortune
