It depends on a few different factors, but mostly it has to do with what tier your have. The higher cost tiers did come with digital copies. The basic boxed copy off of the Backer Portal does not come with a digital version.
Thank you. If I decide to buy an Extra Ditial Download Add-On, do I get a choice of the service I will get it on or does it default to Steam? Or will Obsidian provide the download through their own site? (The same question would go for the DD of the expansion I ordered along with the physical copy)
