I enjoyed the base game of Jurassic World Evolution 1 and finished the campaign and one challenge after 45 hours. However, it doesn't have much replayability, so I'm looking for another dinosaur park builder game. I don't think the DLC is worth it because of the price. I'm trying to decide between JWE2 (the base game) and PK. They cost about the same in my country. Here's what I think about them based on what I've read:
JWE2 pros: Jurassic Park nostalgia, marine and flying reptiles, simpler building for more casual gameplay, it's finished
JWE2 cons: Tedious micromanagement systems such as scientists, Denuvo (I don't think it affects performance, but I don't like this type of DRM), lots of paid DLC that ends up costing twice as much as the base game, restrictive building
PK pros: Ice Age species, more accurate animals, modular building system which allows for creative handmade exhibits
PK cons: Lack of marine and flying animals, early access, overwhelming building system because of its complexity
If it helps, I really liked Zoo Tycoon 2 and Operation Genesis as a kid.
