Additional information: Current state is just a 'starter' for the page. Requires more expansion packs.
A compiled list of expansion packs planned to be released by fans that never came to fruition, whether because they were forgotten or cancelled.
In the earliest stages of Zoo Tycoon 2 modding, things moved slowly and not many breakthroughs for meshing and texturing were prevailent. This often led to many projects being started but never finished, even by teams that were considerably large.
Since these expansion packs often have too little information on them and are not relevant enough for their own page, they are be listed here.
