Pokémon Go fans from around the country—and even around the world—descended upon Grant Park in Chicago this past weekend for the chance to catch legendary creatures and to battle with advanced trainers from across the globe. According to organizers, the event brought nearly 20,000 people to downtown Chicago to mark the one-year anniversary of the game. However, the festival was not free from technical glitches and other crippling issues—Saturday’s event was plagued by constant log-in issues and poor data reception causing game developer Niantic to issue refunds and in-game credits to attendees.
Many attendees who posted images to Instagram didn’t appear to be too upset by the technical issues that affected the festival. Grant Park was transformed into a giant Pokémon arena on Saturday and fans of the game were seen at sites all over downtown trying to catch the virtual creatures.
While the event didn’t go as planned, it brought thousands together on a beautiful day in Chicago. Here’s a quick look at just some of the images and videos from the event posted on social media.
