All esports I follow have great super large tournaments. For League of Legends, it’s worlds, for StarCraft 2 it’s GSL, for CS:GO it’s the Majors, for the FGC it’s EVO. But The International will always have a leg up on them for a simple reason.
The format is better and no fan is ever left feeling like a team was robbed of its chance to go farther. This happens year after year in LoL (G2 so far this year). It sometimes happens at Majors/GSL, but it has never happened in TI. As a spectator, you never feel that a team was screwed over, and that’s because the tournament has such a robust system.
Although it is exhaustive, plenty of tournaments can now pull off what Valve does with TI. At the very least, include the double elimination part somewhere.
