"TL;DR: AlphaStar is the first AI to reach the top league of a widely popular esport without any game restrictions. This January, a preliminary version of AlphaStar challenged two of the world's top players in StarCraft II, one of the most enduring and popular real-time strategy video games of all time. Since then, we have taken on a much greater challenge: playing the full game at a Grandmaster level under professionally approved conditions. "
AlphaStar beats all but the best pro players at SC2. But it's cheating a little bit: uses an API, not image and sound recognition + simulating mouse clicks and keyboard strikes. But it does have limitations on actions per minute and "screen" view, minimap, etc.
