But did it ever really go away? Hundreds of Pokémon Go fans were spotted at sites around Aylesbury today.
You could be forgiven for thinking that the craze was over - but today hundreds of fans turned out for a big gaming event.
Players were spotted at locations in the town centre including Market Square, as well as outside the Waterside Theatre.
One player said: "It was great, it was a big event and there were a few hundred people out for it."
The event was a Pokemon Go Community Day - and the grand prize on offer was a Larvitar, who can evolve into Pupitar and then Tyranitar.
Experts say that this is arguably the most powerful featured Pokémon in any Community Day yet.
