theres really none besides what you mentioned, the isle started the genre and has remained the staple of it, despite all its missteps. BOB is probably the closest, when they dish out updates its usually major, also they have many underlying systems and unique mechanics that could give players who thought the isle had a lot to be desired a ton of fun. But the game will always have its detractors for the visuals, its been stuck at half the playercount of the isle for a long time, the devs dont even try to market it either, all it would take is a major update paired with a sale and also paired with paid sponsorships for big youtubers to play it, that would give it the player bump it needs. Id hardly consider POT true competition for the isle. Yes it does have a vastly more efficient dev team but its an MMO, ur gonna be looking for shrooms to level up rather than looking for ur next prey, also it means fuck all if you die, the game seems to not attract the same audience, if someone wants a survival horror/simulator they'll play the isle, and if someone wants a more fast paced and different dino game they'll play POT, wouldnt even consider POT a survival game. any other dinosim game is likely in preproduction (aka lets see how much money we can gauge out of a kickstarter) phase. You shouldnt go looking for the next big thing, not only because youre gonna be disapointed but if you want a good dino sim experience its already available, play the 3 games you mentioned
