Off the top of my head, there's Temtem and Cassette Beasts that try to mimic the formula more closely, and then there are a bunch of "Pokemon but _____" takes on the formula that you can find with a quick Google. This is "Pokemon but <survival game>". Last I heard, Ark didn't let you assign dinosaurs to a factory or have some of the more RPG systems like boss fights, but quite frankly, I found Ark so obtuse that I didn't play for long.
