I loved the comic serie ( especially first book, the best ) and I liked the PC strategy game. I'm wondering if it's possible on GOG this game in italian language too to play multiplayer effectively.

You can vote for it on the GOG Community Wishlist, to help GOG bring it here. Nice game, by the way! :)

I've been interested in the comic, but sadly I can't find it in English. Tossed in a vote for the game, though.

the main guess is that this game seems incompatble with windows 7 !!! I have physical DVD and game freeze and crash in windows 7 ( cursor freeze on screen ). There are solutions for this crazy bug ?

Yes pity some annoying bugs that block game in windows 7....

If GOG manages to bring it over, rest assured they'll make it run on Win7. It's one of their main "features", in here. :)

I have a physical copy. Great game. Voted.
