Over the years I bought AI War and its first five expansions from Humble Bundle (some more than once). This means I can just download the game from HB, and install it on any computer, without Steam. Of course, HB also gave me Steam keys, which I use for my main PC installation of the game.
I recently bought the sixth expansion, Destroyer of Worlds. That was a good decision. But I bought it from Steam, rather than from HB. That was a bad decision. Because now it means I don't have a DRM-free installer for the *whole* game.
Question: is there a way for me to get a direct download version of Destroyer of Worlds from Arcen, on the grounds that I bought it through Steam? Or will Arcen Games say, "Sorry, pal, you should have bought it direct from us, or from HB!"
Barring this, what will happen if I copy the RuntimeData/Expansions/6 folders from the Steam installation to the direct download installation on my other PC, in order to 'install' DoW there? Will AIWar.exe detect these files and say, "Hey, where did these come from? There's no license key. You have demo status only!" or something?
