Start the right session—and protect the only save file
Build a four-player cross-play party, assign a destination and role, then run an explicit Cross-Save checklist before another platform overwrites the wrong data.
Party board
Cross-play supports two to four players. The first slot is the host; add only the players who are actually joining.
What are you doing together?
Upload once, inspect before loading
Fantasy Life i has one save file. Cross-Save requires the same Epic Games account on both platforms and a deliberate upload from the in-game save screen.
Cross-play is not Cross-Save
Cross-play lets different platforms join the same multiplayer session. An Epic Games account is specifically required for Cross-Save.
Family Co-op is separate
Two people can play on one device with two controllers, but Family Co-op is unavailable during Online or Local Play.
Deluxe bonuses follow ownership
Paid Digital Deluxe content must also be owned on the destination platform or it will be unavailable there.
Official rules used here: multiplayer starts at the Guild Office, supports 2–4 players, Local Play is available on Switch, Cross-Save requires Epic account linking, and Nintendo Switch Cross-Save requires Nintendo Switch Online.
