YMMV: Zoo Tycoon

  • Base Breaker: Zoo Tycoon 2013. Some fans hate the fact it is on the Xbox as opposed to the PC, others are just happy to have a new Zoo Tycoon at all.
    • Further broken by the fact that the new game has 101 animals on the Xbox One and a comparatively paltry 65 on the Xbox 360. Xbox One exclusives include fossa, both of the available species of mongooses, and every single antelope except for one, which is a DLC. (Notably, the game doesn't include any species of zebra, a standard zoo animal. Future DLC, most likely.)
  • Big Lipped Alligator Moment: Santa and a Witch appearing for Christmas and Halloween for ZT1. They fly across your screen for a split second on the in-game Halloween and Christmas. If you're quick (or if you pause the game) you can open the foliage menu and buy special plants- a jack-o-lantern on Halloween and a Christmas tree on Christmas. (Waiting until December 25th in-game is the only way besides cheating to get a Christmas tree, which is the preferred foliage of the reindeer.)
  • Complacent Gaming Syndrome: Regardless of how beautiful or detailed a pre-made map may be, expect one of the first actions when loading up a scenario to be bulldozing everything except for the initial path.
  • Crowning Moment of Funny: In the tutorial for the first game, you're eventually given the objective to delete a section of the lion exhibit with the game telling you they are quite tame. After doing so and watching the lions attack the guests the game essentially tells you "Never listen to us."
    • This leads to an epic Brick Joke for the Dino Digs expansion. After your first dinosaur hatches and you start furnishing its exhibit, the game tells you to delete a section of the fence once more, claiming the dinosaur must be happy enough not to attack guests. After the dinosaur breaks out and (possibly) starts eating guests, the game says "There you go listening to us again..."
  • Good Bad Bugs:
    • In the first and second games, it's possible to buy a male animal just long enough to let it breed with a fertile female, then undo the purchase action so it vanishes and you get your money back. Pregnancy, if achieved, doesn't go away when you do this. The only downside is you can't purchase any other animal or thing before he gets the female pregnant. If you do, the undo option will get rid of that animal or item instead of the father animal.
    • It's always amusing when you place a predator in a prey animal's enclosure, and the prey animal responds with a happy face above it's head, indicating the prey animal's happy with your decision.
  • Hell Is That Noise: The "whoah-who-hoa-ha!" sound the adult male guests make when they get attacked by animals is pretty unnerving, especially when you realize you'll be getting unhappy guests.
  • Most Annoying Sound: *dee-doop* 'Zookeeper 1 can't reach the food dish!' *dee-doop* 'Zookeeper 1 can't reach the food dish!' *dee-doop* 'Zookeeper 1 can't reach the food dish!'
    • Whenever the player clicks on a red area (meaning that the action is not doable for various reasons) the game responds with a loud 'doing'.
    • What makes this especially annoying is that whatever is 'out of reach' tends to be perfectly fine. The problem appears to be with distance, not with any real obstacles, as the game seems to treat being a certain distance from something as it being inaccessible.
    • *dee-doop* "Lion 1 can't reach the food trough! It may be too close to another object!" tends to pop up when you have food troughs shoved up against a wall. While the animals can still access one side of the trough, they sure don't realize that and assume that because one side is blocked, the rest of it is too.
  • Scrappy Mechanic:
    • The adoption system in Challenge Mode in Zoo Tycoon 2.
    • Breeding in the original. Animals seem to just breed at random, and they never seem to mate when you want them to.
    • In the first game, the excessive amount of time given to complete some scenarios. In some cases, it's so bad you will spend more time waiting for the time to pass than actually doing the stuff required to complete the scenario! Fortunately, you can make the game play in windowed mode so you can leave it running while you do other stuff, but it's still annoying and ridiculous. Thankfully, the devs seemed to catch on, as some of the missions in the expansions and all of them in the sequel don't have time limits.
    • In the Xbox One and Xbox 360 Zoo Tycoon reboot, the zoo limit. It's ridiculously low. They give you huge maps, and you can't even fill up 40 percent of them.
  • Unwinnable by Insanity: If you spend too much of your money and don't have enough animals and/or things to sell to get some back, you can be put in a situation were you cannot buy more animals and things, and if you don't have enough animals because they all died or something, you cannot even slowly make more money because you won't get enough guests. The only solution other than restarting or loading a save file is to use a cheat code to make more money.
