Very easy to fill 20k people to watch e-sports here, a vct br final in São Paulo would sell out 50k tickets in 5 minutes. My city that is considered small and only has 1 million people filled a stadium with 15k people a watch party of the CBLOL final in 2016.
Come to IEM Rio 2022 friend, there will probably be a free watch party outside the arena with thousands of people, unfortunately the tickets sold out in less than an hour.
