Got up early to download the update and dlc while I was getting ready for work. (Sadly, my boss doesn't recognize Planet Zoo Holidays!)
Came home from work ready to play and did some fairly basic habitats for caiman, otters, penguins and the turtle. Will definitely be building each of them a more elaborate "pretty" habitat in the future, but just wanted to get them in the game to see how their mechanics worked and watch them a little bit. I did get all of them to dive, and even had 2 baby otters in the process. Held off on getting any seals until tomorrow because they were a bit more expensive. All the ones for conservation credits were going at or near 10,000 during the hours that I was playing, which I suppose I could have afforded, but I didn't want to blow all my credits in one place. There were some cash ones from Frontier, but I hadn't built up enough of a surplus in this new franchise zoo to pay for everything in cash, and I figure the credit market will stabilize by tomorrow, so why rush?
I noted that the penguins can have up to 500 adults (Challenge ACCEPTED!), and that they can also be walk-through habitats. So now I'm toying with the idea of a cold-weather park where the penguin habitat is built to look "free range" (like you see for peafowl) with all guest paths being part of the giant penguin walk-through, and then other cold-weather animals like seals, reindeer, arctic wolves, polar bears, etc. being the "exhibits" that guests go around and visit -- from within the penguin walkthrough itself! I'll need to do the math and figure out how to get keepers to take care of the whole thing, but potentially such a habitat might dwarf the polar bear requirements.
