Players who made history in competitive gaming

It turns out that some players who achieve legendary status in competitive gaming do so not just by being incredibly skilled, but by fundamentally changing how their games are played. I was reflecting on this recently, thinking about how some individuals push the boundaries so far that their influence is felt for years after they stop competing. It's more than just winning tournaments; it’s about innovative strategies, mechanical mastery that seems impossible, or even inspiring entirely new generations of players. For instance, I recall watching one particular competitive game where a player introduced a completely unconventional tactic that became widely adopted. Who are some of the players you believe truly made history in competitive gaming and why?
