Nearly two dozen Pokémon Go Fest attendees are filing suit against Niantic, the game's developer, seeking travel reimbursement following last weekend's event, where most people were unable to play the game.
Chicago-based attorney Thomas Zimmerman said he was contacted by Jonathan Norton, a California local who traveled to the area for the event. Since then, Zimmerman told Polygon that ”20 or 30" others have joined the class-action suit.
”The issue is, what was promised, what was the incentive that people relied on and the representations that people relied on to buy a ticket and make travel plans and fly to Chicago to participate in this festival, would they have done that had they known that that was not going to be lived up to and they weren't going to get the experience that was represented?" Zimmerman asked.
