I feel like the short dinosaur lifespans in JPOG were to give the player the chore of replacing the dinosaur stock every few ingame years as it only takes about 4-5 ingame years to receive a five-star park. So that way, it could give the player something to do while getting five-stars or after fve stars if you wanted to keep playing. I also wonder if the detail of decaying bodies is in JWE like it was in JPOG and how graphic the violence will be. In JPOG, the only somewhat gross/violent things that happened were decayed, and rotting corpses, small blood splatters when a dinosaur was attacked, and smaller dinosaurs/goats/ and humans being thrassed around and swallowed whole by large carnivores.
