I wanted to buy the Gold Avalon pack via Steam because I find the game interesting with a lot of potential, only to get returned with the error that I require the base game in order to buy it.
Is the base copy of the $15 game seriously not included in a $70 pack, or is it a Steam bug?
Thanks in advance.
