Pokémon Go reached its highest player count since its 2016 peak, according to a study from SuperData. According to the study, the game generated $104 million in May, up 174% year-over-year.

SuperData attributes the rise in players to Pokémon Go’s “walkabout” gameplay, which is naturally more suited for warm weather. Pokémon Go recently received the long-awaited trading feature, which may have brought players back to the game.

The player count also coincides with the announcement of Pokémon Let’s Go Pikachu and Eevee, Nintendo Switch titles that will interact with Pokémon Go when they launch on November 16.
