In the final days of August 2026, HoYoverse Korea marked six years of Genshin Impact not with spectacle alone, but with a quiet wager: that millions of players, walking their own neighborhoods, might collectively summon a forest into existence.

It is a small but telling experiment in what becomes possible when digital community is pointed at ecological consequence.
