I feel like you are missing the point of the games story.
In the lost world movie or the books fans were introduced to the five deaths, but it wasn't really covered in the movies as to why they are the five deaths, sure after watching the second move people may assume that the islands got their names from the dinosaurs killing everyone. But that was in fact not the case.
Through the story mode of this game we not only get to see every island of the 5 deaths but can find little hints as to how the islands got their name, and which island is which of the 5 deaths. In addition if you complete the memos portion of the Ingen database you will see how Dr. Wu interacts with the other characters on the island and get some idea as to his intentions. This whole game is as if the first 4 movies took place but went a bit differently than they did in the movies. Which lead to the creation of 5 new parks on each of the five deaths. In some way this is a bit ironic as We are literally making the 5 deaths into a place where people can literally go to and never return.
And I think this game is actually really creative and is both a park management as well as a crisis management. Because lets face it in a dinosaur theme park we need to manage it like a theme park, but we also face problems that a zoo might face. Except unlike a zoo our animals are much larger and stronger, and even more capable of endangering our guest. As such it is a crisis management. Heck they even added lawsuits which is both a park management and crisis management. Even theme parks have attractions go wrong from time to time, and people get hurt.
And having limited space on an island makes you get creative, especially since you can come back with new dinosaurs and adjust your park as you see fit.
I personally looked at my islands( after getting used to the games mechanics) and started to plan my park accordingly, I found myself then adjusting my plan to fit the guest's needs and to 5 star my parks. but it had to be done with creativity.
I'm sorry, but how does giving backstory to how an island archepeligo got their names make for a good story or warrant setting a dinosaur game there? What does it bring to the game from a story or gameplay point of view? Does it expand the JP lore in any meaningful way? Does it consitute a good premise for a story? Is it EVEN a story? I really don't think it is.
Moreover, the reasoning behind having limited space in a game designed to allow the player to create the Jurassic Park of their dreams, falls very flat. Restrictions in a game that is fundamentally designed to allow creativity is NEVER a positive and as a result one of the primary complaints levelled at the game is that the islands are far too small. I would also contest that the game is 'really creative'. The lack of customizable enclosures and artifacts throughout the park severely limits what players can do. The end result is that every single park fundamentally looks identical.
