Hello!

Is there an option to upgrade to Imperial Edition from explorer edition?

I am also interested in this. Is it possible?

The devs response to this is that it will be available at some time but no definitive ETA.

The game is the same for all editions. you get a few more items and whatnot that is pretty much useless by early Chapter 1. plus you get some out of game items. soundtrack, pdf map, ect... but nothing that changes the game itself....

The game is the same for all 3 versions.

Also interested in upgrading.
I would like the soundtrack and am happy to support decent developers (lord knows they are in short supply these days).

I note that steam does have a royal edition upgrade, hopefully it will arrive here on GOG soon.

My fingers are crossed and my wallet is waiting.
