My (not so) little wishlist... will probably update at some point... and repost... even if there's probably no point in doing so...
1. Mod Support
An absolute necessity; modding and custom content can extend the longevity of a game long after the developers are done with it. Just look at Zoo Tycoon 2; ten years later and it still has a thriving mod community, updating and modernizing the official game while adding all kinds of new content.
2. New and Improved Infrastructure Elements
The current building options--the decorative and landscaping options in particular--appear to be quite limited at the moment... more options never hurt, and allow for better customization of our park's appearance.
- New Infrastructure
Bridges and elevated path ways, for both civilians and vehicles.
Gates to allow tour vehicles to venture between pens, including the Jurassic Park gate.
Concrete moats... an alternative to fences.
Wooden fences, chainlink fences, railing fences, and hedges; for keeping guests out rather than animals in...
Classic Jurassic Park style buildings... or at the very least, give us the Jurassic Park Visitor Center that functions like the Innovation Center...
- New Attractions
Actual transportation to get guests on and off the island; boats, planes and helicopters.
Make the Monorail system an actual ride/transportation device and not just how guests get into the park.
The classic Jurassic Park tour.
The safari truck ride seen driving amongst the Gallimimus in Jurassic World, or something similar...
The kayak ride from Jurassic World and other such water and river rides.
What about a helicopter tour ride or the Balloon ride from JPOG? Some form of aerial tour ride would be good...
Pay to use binocular stands are a common Zoo attraction...
Some regular theme park attractions might be nice... what about a Ferris Wheel? Or a Jurassic-themed Carousel?
- New Feeders
Different types of animals for different carnivores; small pigs, large cows, and so on... all requiring different hunting strategies and fulfilling different amounts of hunger.
An aquatic feeder for piscivores; can only be put in water and dispenses fish.
- Landscaping
Topiaries, flowers and flower beds, decorative trees and bushes, fountains, sculptures, statues and signs for the guest areas.
Different terrain types; everything being grass and island jungle is boring and unrealistic. Grassland, scrub, desert, savannah, temperate woodland, swamp, and so on...
Different plant types; we need plants--trees, flowers, bushes and so on--to match those terrains too...
The ability to select and place individual plants--rather than the non-specific plant tree and plant bush brushes currently in the game--would be a huge improvement.
Rocks... because why are there no rocks?
- Guest Amenities
Benches, trash cans, picnic tables, light poles and decorative lighting.
Vending machines, ATMs, drinking fountains.
Tour guides and group tours.
Security devices to protect guests from other guests.
Restrooms.
3. Island Maker
While the included islands will surely be nice for mission mode, when it comes to sandbox gameplay I really want to have an island of my own design to work with. The design tools I would hope to be very extensive, allowing me to create vast fields, mountains, cliffs, ravines, rivers and lakes, as well as give me access to all landscaping tools (such as the ones I listed above *wink, hint*) to create the island paradise of my dreams before filling it with it dinosaurs.
4. More Animals
