Read full description

Begin as a human explorer and survive the island long enough to awaken your true apex form. Evolve into a roaring T-Rex, drive transport trucks through dangerous terrain, rescue trapped dinosaurs, and expand a living sanctuary you control. This is not a one-loop dinosaur sim. One session can send you from trucking missions to emergency rescues, from park decisions to open-world predator action. Hunt, relocate, protect, and dominate in a game built for players who want to play as the creature, not just watch it.

Verdict

The call

T Rex Evolution Open World Sim's advantage is update cadence (every 3 months vs every 6 months). On price, ads, in-app purchases and monetization model there is nothing between them.
