When Divinity 2 came out in January, I ended up buying a retail copy. Since then, partly because of the DRM on Divinity 2, I have turned away from buying games in a retail store.

Will the FoV expansion pack on steam be able to interact with the Divinity 2 game installed on my computer already in any scenario?

IE: If I buy FoV on steam, would I have to buy the original D2 on steam as well. If I would, would my saves be able to transfer?

Thanks and Gig'em
