Shortly after PC was released, I did a comparative study of peep preferences for 1 type of shop over another. Turns out, peeps greatly prefer certain gifts, food, and drink over others. Since then, we've gotten beaucoup new shops plus vending machines. So it was time to do the test again to see how the new shops fit in with the old, and whether any old peep preferences had changed.
To do this, I created a simple park to bring in about 1800 peeps. Then I put all the different types of shops in courts near the middle of the park, so that all the travel distances to the same types of shops were about the same. Then I let the game run for 4 months and averaged how many customers each shop got. Then I changed things and ran another 4 months, repeat.
Here's what the park looks like. The shop courts are the blue paths. From left to right, you have the gift, drink, food, and vending machine courts. In this pic, I'm testing food vending machines. Later on, I deleted all them and replaced them with drink vending machines.
Here are the results:
TL/DR VERSION:
* Balloons 4x more popular than hats, hats 2x more popular than mementos.
* Vending machines are universally hated and despised even if there's no other choice.
* Energy drinks don't sell if you have benches in the park.
* Most popular drinks (80% of all sales): smoothies, juice, water
* Nobody ever wants coffee.
* Burgers are overwhelmingly the most popular food, followed by sushi, ribs, Mexican, and hotdogs. These are 80% of your sales.
* Everybody still hates frites and donuts.
GENERAL TRENDS
Gifts:
No changes from before. We still have the same 3 types of shop (balloons, hats, and mementos) and peep preferences for them are still the same. Everybody wants a balloon, some want hats, and hardly anybody wants a snowglobe.
* Balloons: 84/month
* Hats: 20/month
* Mementos: 9/month
Shops vs. Vending Machines
This works the same for both food and drink. Peeps would pretty much rather die than use a vending machine, even if there are no shops of the same type (food or drink) in the park. When both shops and vending machines are open at the same time, the vending machines get zero business. If only the vending machines are open, the vending machines get ALMOST zero business.
NOTE: This is more extreme than seen in real parks, due to the small size of this test park. In real parks, I've found that vending machines in the middle of very long paths with no attractions (such as going down a cliff or crossing a long bridge) get slow but steady business. In general, however, vending machines are highly UNpopular.
Old Food and Drink Preferences Remain
Prior to all the new shops, certain food and drink were far more popular than others. For the most part, those same types have retained their overwhelming popularity with most of the new shops getting little business. The following details will show this.
Benches and Energy Drinks
It is still the case that if you have a lot of benches in your park, you'll hardly sell any energy drinks. However, if you take away all the benches, energy drinks become almost the most popular.
SPECIFIC RESULTS
(all numbers are average customers/month over 4 months)
Drink Shops with Benches
Smoothies have catapulted into the lead (they used to be only as popular as shakes). But otherwise, the order is still about the same as always with water and juice still far ahead of anything else. And still nobody likes coffee.
* Smoothie: 83
* Juice: 66
* Water: 52
* Slush: 23
* Soda: 18
* Shakes: 12
* Energy: 4
* Coffee: 2
Drink Shops with NO Benches
Smoothies are still the most popular but energy is now a strong #2 with water and juice still rounding out the top-sellers. And even without the free energy of benches, STILL everybody hates coffee
.
* Smoothie: 83
* Energy: 59
* Water: 40
* Juice: 33
* Soda: 11
* Shakes: 7
* Slush: 6
* Coffee: 4
Drink Vending Machines
With the drink shops open, the machines got zero business. The below thus only shows the results of 4 months with the drink shops closed and only the machines open. Note the HUGE fall-off in overall sales between the shops (above) and the machines (below), from several hundred to less than 10. Peeps really HATE vending machines, even though they're about 1/2 to 1/4 the price of the shops.
* Pipshot: 6
* Cosmic Cow: 2
* Streetfox: 1
* Gulpee: 0.25
Food Shops
Of the original types of food, burgers and hotdogs are still by far the most popular and the 1st batch of new food (with things like Missy Good) are still unpopular. However, the Worlds Fair foods range from very popular to not so much, but still better than the less-popular original stuff.
NOTE: The 1800 peeps in this park weren't enough to support all 18 food shops: 7 shops got zero business over 4 months. Thus, I can't rank all the shops here with so many ties. Still, the fact that 7 shops got zero business while others got so much shows the strength of peep preferences. Strangely, this list includes both pizza and tikichiki, both of which were fairly popular originally. It seems the new shops stole their business. But still nobody likes frites or donuts.
* Burgers: 48
* Sushi: 25
* Ribs: 22
* Mexilante: 18
* Hotdogs: 15
* Burritos: 13
* Wurst: 8
* Gelato: 5
* Vingt: 3
* Chow Mein: 0.25
* Ice cream, donuts, pizza, sweets, churros, frites, and tikichiki all got 0.
Food Vending Machines
Again, these numbers come from having the machines open and the shops closed. Again, there was a huge loss of business because peeps just hate vending machines.
It might appear that peeps prefer different vending machines than they do shops. However, the sample size here is too small to justify that. In general, the machines that got any business at all only serviced 1 group in any single month, and groups vary from 2-6 peeps. Thus, machines showing a 4-month average of 3-6 peeps got 1 group of customers per month, so are all about equal. Those with smaller averages did not get customers every month, and some got zero business at all.
1 group/month:
* Mexilante: 6.25
* Gelato: 5.75
* Churros: 5.5
* Ice Cream: 4.25
* Chow Mein: 3
1 group every 2 months:
* Sushi: 2.25
* Wurst: 1.75
* Sweets: 0.75
1 group in 4 months:
* Sweets: 0.75
* Tikichiki: 0.75
* Frites: 0.75
Zero business over 4 months:
Ribs, Vingt Sept, pizza, burritos, burgers, kebobs, hotdogs.
