Boy, I'm tempted by this. I own the base game, and can pick up all the DLC for $10CDN.

Problem is, I only bought the base game because GSC Gameworld assured us that the Linux version of Cossacks 3 would come to GOG. I've emailed them several times since the Linux version was released on Steam, and haven't received a response.

I hate when they write " and more " on the front banner .

perhaps you can ask GOG?
don't know if that will help though?

Great game.
But be aware of the missing, Steam-only, level editor.

Serpent in the Staglands - -70% - matched historical low (highest percentage discount and USD price, new low as EUR price due to recent conversion rate update)

Yeah, considered it for a moment... But needing to go out and buy a PSC is a great way to prevent any impulse buys :)) Besides, still a backlog for likely the better part of the next decade and a difficult game means I'm very likely to get frustrated and probably give up even when I'll get around to starting. Plus, $5.99 is the most I spent on a game on GOG, and one was for the community giveaway and I'm yet to even install any of the other 3, so... Yeah, maybe someday, assuming it won't end up with any higher-than-base regional pricing by then.
