Is there any chance of getting either of these (or both!) made available for Mac users?

I checked my old discs and I think both are hybrid discs (both mention Windows and Mac on the disc itself) so it's unlikely that the rights for the Mac version are held by a different company. Just let gog.com know you want it and maybe they'll release the Mac versions soon.

Seconding a desire for a Mac version of Imperialism.

I had the Mac version years ago. I think one of the difficulties is that it ran on OS Classic. I'm not sure what kind of emulator you would need for it.

Well, they've managed to make other OS Classic discs I have work, so hopefully it will be possible sometime in the not-too-distant future!

Not trying to raise the dead or whatever, but seeing as how my wife came up playing this game on Mac and now has a Mac and can't play it off GOG... I'd really like to see this release on Mac as well.
