Cross-Play, Cross-Save and Co-op: A Buying Checklist
Cross-play, cross-save and cross-purchase describe different features. A game can support one without the others, and “co-op” may mean local split-screen, private online sessions or shared-world multiplayer.

Separate the three cross-platform promises
Cross-play means players on different platforms can join compatible sessions. Cross-save or cross-progression moves progress through a publisher account. Cross-purchase or Play Anywhere can grant licences on more than one system. None automatically guarantees the others.
Define the co-op session you want
Local co-op requires players on the same device and may need multiple controllers. Online co-op uses separate devices and often separate licences. Some campaigns are solo-only even when another multiplayer mode supports teams. Confirm the exact mode and maximum party size.
Accounts and subscriptions
Console online play may require a platform subscription. Cross-progression often requires a linked publisher account. Link carefully: progress on two separate publisher accounts may not merge, and unlinking can have cooldowns or restrictions.
Group purchase checklist
- List every player’s platform and generation.
- Confirm cross-play for the exact mode.
- Confirm supported party size.
- Check required online subscriptions.
- Check publisher-account linking.
- Buy the correct platform licence for each player.
- Test voice chat and privacy settings before game night.
