Will my save carry over if I buy the physical game?

Hi, Kalee! I'm Kim, an Independent Advisor and I’m happy to help you today.

Yes. whenever you sign in to the Xbox network, your game data gets saved online. That means, whenever you next play the game—if you buy it, if you play it at someone else's house, or if you come back to Game Pass you'll be able to pick up right where you left off.

Only the season pass carries over...

If you buy any individual DLC for the game, it will not carrie over.

So you should really buy that season pass if you want all maps on both console, saves you quite a bit

And I think you need to buy the season pass before 31th of May, to get it on both consoles.

Achievements carry over. But some story mode games saves don't carry over unless you have them stored in the cloud or have external HDD and save then take it to XBOX1. Not sure if flash drives work yet for XBOX1? I know my GTA5 story mode didn't carry
over only online rank and achievements. Story mode I started over. If I had a cloud save then it would of worked.

What's the incentive to buy an 8 month old game again apart from the graphics looking a little better? I've played the game and completed it. Didn't like the multiplayer at all and moved on.

If I buy the new version, my saves carry over from the 360, so i'm loading up an already completed game!

Pointless!

works the same way as halo mcc, all save data and game progress carried over for me, including all cheevos that opened all my steam cheevos up.

you sign in to the xbox live servers to play and all game saves for that are carried over. i know i play both via steam and console. its the same with sea of thieves too.
