I have asked a similar question of both MS & BF about making expansion files available as new creations seeing as they have no plans to add to the ZT 1 games in the future and the answer is NO. We can not edit files from the expansions and make them available for those who do not have the expansions. You will have to purchase the expansion or Zoo Tycoon Complete Collection to be able to have the files made available after the release of ZT. The only files available are the CC content files that we have been given permission to make available and they will be made available as soon as the new downloads database is complete.
