While I'd like to own those skins as I already have four Velociraptors in my park I did even name after the four movie raptors, I certainly don't like the fact one has to pay for it.
Frontier, sorry, but seriously? The game wasn't cheap when it came out, and let's be honest, it was half finished. Frontier did an amazing job on expanding it, but it is still lacking in several aspects (dinosaurs are still walking through each other, the InGen database is a mess, guest and shopping management is lacking immersion). We even had to pay for additional content that granted the Indominus rex an ability that should've been part of the base game already. And now we shall pay even more (not much, but still) money for a tiny addition that doesn't change anything besides four skins? As cool as they are, no.
Those skins are movie stuff and facts, it could've been part of a free update like the Nasuceratops. But no, of course we can buy that as well... A dinosaur pack here, a DLC there and now some skin and cosmetic additions that don't change anything besides four darn skins. I sometimes have the feeling players who bought everything additional to this game spent in the end way more money than this game is actually worth.
Sorry for this little rant, but that's just my opinion.
