Sorry if this contravenes the forum rules in any way, but I just tried to buy Beyond the Sword online from a well known site that starts with S and rhymes with "Team". And I got this error message: "Your transaction failed because you are trying to buy a game that requires ownership of another game you do not currently own. Please correct the error and try again." I own a copy of (vanilla) Civ 4. Are these *******s trying to fleece me by making me buy it again? What other options do I have for buying BTS?
