The beautiful thing about being thirty hours into Jurassic World is that you can be done - like I am - or you can embrace all you’ve learned and build a Jurassic Park that would put John Hammond to shame. Having not touched the sandbox, I’m sitting comfortably at thirty hours. I’ve since completed the storyline and unlocked the sandbox mode as well as every building and dino available to me. The last time we checked in Jurassic World Evolution, I was only eight hours in - building my first T-Rex on the game’s third island. Jurassic World Evolution is an excellent park builder.
