I honestly feel like this is a good ending for Planet Zoo.
Not the best ending, but it could have been a lot worse.
And I feel like it should be an ending.
We already saw a pretty noticeable drop in quality with the last two DLCs, and I get why people would want more animals and more content to be released (heck, I would too) but I think that this situation can't go on forever. We ask for new animals, we get new animals, but at the same time the team at Frontier gets smaller and so the quality drops.
The more I look at the newest Zookeeper's Pack, the more I see that Frontier still tried hard, but didn't really reach the same levels as last year. It's still good, but not nearly as great as Eurasia or Oceania or Tropical... And I kind of feel bad about it. Everything gives off this sort of tired energy, like it's struggling to find the strength to go on. I feel like we won't be as lucky next time, so I personally believe that Planet Zoo should end here before the situation gets worse.
But maybe this is just me humanizing what is in fact just a company that in the end of things just cares about the money it makes...
