Nintendo published guidelines for businesses and organisations using Animal Crossing: New Horizons as a platform.
According to these guidelines, companies using the game are allowed to share custom designs with other players, invite them to their island, and share their 'dream address' (which allows players to visit each other without having to use the in-game airport).
Businesses can also upload screenshots or game footage to "family-friendly" websites, Nintendo said, as well as social networks.
However, Nintendo warned companies about taking part in activities that go beyond the game's rating (PEGI 3).
"Please refrain from using the game inappropriately or creating any content within the game that would be considered vulgar, discriminatory, or offensive," the guidelines read.
