The original JP buildings/vehicles are a dealbreaker for me. If it's not announced to be either in the game or in an immediate DLC, I'm not buying the game. It's not a Jurassic game without that look, it's just a generic dino park builder.
Yeah it's a bit of a disappointment that we don't get to build the 1993 park on Nublar. But we will probably get JP themed assets as DLC. There is enough people asking for them to make it happen.
