Pokemon Go Fest Chicago took over Grant Park on Friday, drawing crowds that lined up early to get inside the park as the gaming festival began its run through Sunday. Kylee Miller was among those on the ground, planning to catch them all while providing live updates from the scene.

Thousands from around the world are meeting in Chicago for the festival, which is built around exclusive gameplay and different habitats spread across Grant Park. The event gives the city a burst of energy at the start of the weekend, with the park serving as the center of a global gathering that runs through Sunday.

This year’s turnout comes with a sharper sense of purpose from organizers after the last festival at Grant Park in 2017 ended in a lawsuit. That first-ever Pokémon GO Fest was plagued by long lines and app glitches, problems that left a lasting mark on the event and shaped the way this year’s version is being staged.

Organizers are going all out this time, trying to avoid a repeat of the chaos that followed the debut. What is not yet clear is how large the crowd will be by the end of the weekend, but for now the answer is visible at the gates: fans arrived early on Friday, and the festival has already taken hold of one of Chicago’s best-known public spaces.
