I'm pretty sure the original versions come with the EEs, you just can't purchase the original on its own any longer, but I think that's more on Beamdog than on GOG. Besides, I'm still running off of the installers they gave me back before Beamdog's versions were a thing. Because you know, installation media that I can use after all their servers are dead and gone is pretty fucking nice to have.
