Starfinder Which SF 1e Books Will Be Useful With SF 2e?

[Dragonhelm]

With the new edition coming, some of the current rulebooks will be dated. Perhaps none more so than the Alien Archives.

Just curious, which of the SF 1e books do you think will still be useful with SF 2e?

 

[Retreater]

The pawns will probably still be useful. And the flip-mats.
As for the books, maybe the lore sections of books like Pact Worlds and Near Space?
Other than that, probably nothing.
