Instincts is great, but I'm still technically correct (the best kind of correct) because it was a reimagined port of FC1.
I just looked up the Wikipedia article to check how many versions there were in total. There was the original, Instincts, Instincts: Evolution, Predator, Vengeance and Paradise Lost.
They pretended Insticts was a port, but as I understand it, almost nothing is actually the same. Especially with the feral powers that make instincts what it is
