Thanks to everyone for your interest and specially those who have been understanding with how much work it takes to make this list and keep it updated.
I've been just 3 days on holidays and wow, so much new stuff to take in!
So, I've tried to consider every point that has been raised here and also my current position to reach a final decision. And my decision is that there won't be a new meta-wishlist iterarion from my part. However, from this very moment I will allow voting for 5 additional animals to the people who have already submitted a list (making it 25 animals in total). Everyone, regardless of how many of their 'essential' animals made it to the game already, is allowed to make 5 extra votes. I think this is fair for everyone.
'Why 5?' Some people might ask. Well, I took a look at the first 30-40 submitted lists and most of them had 2-6 animals that were later implemented in PZ. Also, given that we still don't have aviary animals (it's expected but not confirmed) and that we should be getting presumably at least 22 more habitat animals in PZ (assuming 2 more animals packs and 2 more scenery packs), I think 5 extra animals is a good figure.
I know some people might not like this and won't agree with this but I honestly think it's the best option to:
-Allow extra votes, particularly thinking of the people who saw many of their resquested animals disappear from the list (cause of being added in PZ).
-Keep this maybe not perfect, but very valuable list with all its valuable data (>300 participants and counting, I doubt a new one would reach this figure).
-Give me less work. Starting a new meta-wishlist completely from scratch is extremely time consuming. Allowing a specific number of votes to those that had a number of their requested animals added is also a hell of a lot of work. Adding 5 additional animals from everyone is still some work but a good compromise. I'm submitting my PhD soon so time is very precious to me right now haha.
I hope you all understand my reasoning and also my current circumstances. If anyone wants to start a new meta-wishlist I would support it and of course, participate! Submissions of your 5 additional votes are now open! The OP will soon be changed since this will now become the 'New 25 essential animals meta-wishlist'.
