I'm thinking about getting GalCiv3 for friend, but multiplayer is very important to them. Does crossplay work between Steam and GOG yet, or are there any plans for that? Do GOG servers typically have multiplayer games up?
I never tried multiplayer, but i am not seeing any complaints about it over on the Galciv3 forum, so i guess it must be working pretty good.

I would say give it a go....

It would be hell fun doing a noob multiplayer were no one knows how to play, that would be a riot! lol
