A ripoff would be the exact same animal roster without any improvements to quality just to make sure every DLC species was accounted for from the start. I.e., what you're asking for. Because expecting the full 200+ roster, plus more, plus other general improvements is an absurd fantasy.
I keep seeing people saying this, but it's full of yet more ridiculous "hybrid" dinos, this time in the form of mutants. Also complete with it's own Short Round character, apparently, which stopped being fun after The Lost World. And I'm saying this as someone who liked Jurassic World (the sequels less so).
I'm very pumped for JWE3 - I'd buy it for the waterfall tools alone - but not so much for Rebirth. The d-rex looks stupid; it actually reminds me of Giganto from Marvel Comics. Belugasaurus.
