Know the officially listed play modes
Steam lists online co-op for the PC release, and KRAFTON's PC FAQ describes a host plus up to five visitors. Nintendo lists one player on a single system, and two to four through local wireless or online play on Switch. Those are platform-specific statements, not one universal player limit. The host starts a multiplayer game and visitors bring a character with their own inventory.
The PC FAQ says visitors can take items home after a session, and the world remains active while the host plays. The 2023 Summer Sun patch increased PC multiplayer to six and introduced proximity chat. Nintendo's store listing does not promise every PC session feature on Switch. Check the store page for the platform you actually plan to use before inviting friends.
Check platform-specific unknowns before buying
KRAFTON explicitly says Steam-to-Switch cross-play has no current plan. It describes cross-save as a future plan rather than a working feature. Nintendo's local wireless support is not proof of split-screen on one system. If either feature is essential to your group, check a newer official statement before buying.
Steam and Switch updates can arrive at different times, according to KRAFTON. The 2026 Switch update changed which PC content had reached the console. Check the version, session permissions and mode before promising that two players can follow the same tutorial. A verified date for live cross-save remains 待确认 here.
