Sync libraries, spot shared titles, and plan from Discord. Cross-store library

Friend owns the game on Epic, you on Steam. Can you still play?

If you each own the title on your store, it counts toward shared games. PlayGrid shows that overlap before you pitch co-op. Ownership first, then confirm the game supports cross-store multiplayer.

Same game, different store can still work

Many co-op titles are on both Steam and Epic. If you each own a copy on your store, you can usually party up. PlayGrid counts that as shared ownership when both libraries are linked.

What fails: only one person owns the title, wrong edition, or DLC one side does not have.

Check overlap before you buy or refund

Both link Steam, Epic, and EA in the browser.
Add each other on the Friends tab by email.
Open shared ownership for tonight's roster.
Shortlist 2-5 titles everyone can launch. Schedule one session with the pick pinned.

Duos vs full squads

Pairs who always split stores should also read the Steam + Epic duo co-op guide. Larger groups use the same overlap filter with more rows.

Shared ownership is not the same as cross-play

PlayGrid answers whether everyone owns a launchable copy. Whether Steam and Epic players can party together depends on the game publisher. Not on PlayGrid.

After overlap, confirm cross-store multiplayer in the game's docs or patch notes. Then pin edition and DLC notes on the session card before voice.

Common cross-store mistakes

Only one person owns the title. Overlap will not show it.
Epic free game claimed on one account but library not synced in PlayGrid.
Standard vs deluxe edition mismatch, or DLC one side lacks.
Same title listed twice after sync? See Steam + Epic duplicate grouping.

FAQ

Does PlayGrid merge Steam and Epic into one purchase?

No. You still need your own copy on a store you can launch. PlayGrid compares libraries so the group sees honest overlap.

What about cross-play between stores?

PlayGrid lists shared ownership. Whether a title supports cross-store multiplayer is up to the game. Pick from the overlap list to avoid guessing.

Do Epic free games count for cross-store overlap?

Yes after you claim them and sync your library. Free claims are owned titles. Same as purchases when everyone on the roster has a copy.

What if we own the game but cannot connect in-game?

Check cross-store multiplayer support, edition match, and required DLC. Ownership overlap only confirms everyone can launch. Not that the publisher enabled cross-play.

What about GOG, Xbox, and Ubisoft?

GOG, Xbox, and Ubisoft are on the roadmap. Today PlayGrid ships Steam, Epic, and EA with friends, sessions, and Discord Activity.
