True speedrun

A true speedrun is truly the fastest way to beat a video game. It is different from normal speedrunning in that a true speedrun aims to reduce total play time. Normal "speedrunners" spend a significant amount of time playing the game multiple times and practicing in order to beat games as fast as possible. The fastest way to win a game is to play the game once as fast as you can the first time, and never spend time on it again. After you beat the game, playing it again may lead to decreasing your single-run speedrun time but leads to increasing your total play time.

Alternative definition: "beat" the game literally by breaking the console or game disk (by far the true fastest method).
