Good game, and more content for a cheap price is good...now if only the Mac/Linux versions were on GOG like the DLC says they are (but they're not), that would also be good.

Curious to see a DLC four years after release. Agreed. That goes doubly so for self-published title. There's no excuse for only dumping the Windows version here. GOG really should be insistent about that when there are no other barriers for doing just that (i.e. third party ports a la Feral Interactive/Aspyr).

Nice, been waiting for this one!

Great price and size for the amount of content and hours you'll sink into this, if you can get past the green propaganda that is. :)

EDIT: Shame we can't just buy the OST after having bought the main game. Should at least be an option to do that or a way to upgrade.

I'm not sure, I understand this right. The soundtrack is available separately here:

Am I misunderstanding what option is wanted?

Interesting. I've never run across this game even though it looks like it should have come up in my searches, based on the types of games I gravitate toward. I'm pretty sure I would have remembered one that used what seems to be triangular tiles instead of squares or hexes! :)
