7 years and still going strong, even in 2020. To celebrate they're running a anniversary event. And every anniversary event when you're about to finish the event quest you get a cutscene to be greeted by Yoshi-P himself, Naoki Yoshida. And with patch 5.3 they started the collaborations such as Yo-Kai Watch and the next chapter of the Nier: Automata raid series.
Speaking of 2020, did you hear that they cancel the FFXIV Fan Festival 2020-2021 events for North America and Japan due to the coronavirus? No word on Europe's cancellation yet. Maybe they should run a online event to stay safe, just like Blizzard is planning to do with BlizzCon.
