Wow what a friendly forum ...
Oh and thanks for that referral, how funny, did it not occur to you that I might have checked Google already? From the sketchy information available (even on Stardocks own site) it seems us Europeans have access only to the Kalypso owned version (mentioned above) which I think aren't curently patch supported which beggars the question why on earth buy those as I hear the game is quite buggy without current patch support.
Again this is all hearsay from other forums, random articles, reviews (All found on Google) but they arent definitive and they sometimes contradict each other, forgive me for wanting to buy the right version and support Stardock. Christ it wouldnt kill someone to take 5 minutes to explain it to a new player, you have to remember as a person new to this game, I can see about 5 or 6 different boxed and D2D versions to buy they all wildly vary in price (from £6 to £30) and are published by different people, I fail to see whats so simple about that.
