I wouldn't say this is a good measure of what to expect.
Oh no, i didn't mean that just because they were featured in ZT, they will be added in PZ. It was just something i noticed about that list, and ZT hits right on the nostalgia for me so i approved lol I would love if the whole ZT roster is included in PZ.
But even so i think PZ has an overall better roster than ZT had at this point. Like i said the only BIG NAMES missing imo are the dromedary camel, the black rhino and the nile crocodile.
I was really fond of the caracal, the gibbon, the secretary bird (mostly), the gelada and the gerenuk from ZT, and a lot of people really seem eager to get a spectacled bear as well, but i would not care at all if things like the ethiopian wolf or the javan rhino never make it into PZ.
