The point of the game is to try to make a park with dinosaurs, that will fail, causing the dinosaurs to escape and eat people. This appeals to gamers who are of the type who played The Sims and loved putting the sims into small doorless rooms and lighting it on fire, or putting them in pools and removing the ladder.
Basically, it's designed to fail, both because there are natural disasters that you cannot adequately prepare for, and the human element (the three "factions" will actively sabotage shit like cutting off the power if you support someone else, which you have to because it's zero-sum). While this is actually quite faithful to the message of the book, it's FUCKING DOGSHIT from a gameplay perspective.
