I hear the building hotkeys are very very different from the Planet series which is throwing some people off; but the tools are every but as powerful, and I’m invested enough in dinos and the Jurassic series to power through. And if you’re coming from JWE 1 or 2 rather than the Planet games, I think it’s just a straight upgrade. Even if you hate the piece by piece building and think it’s too complicated, the base game comes with more themes than JWE2 had with all DLC and you can download stuff from the workshop.
I didn’t realize there would be other JWE players! If there are enough of us, we could do some kind of community built park - sharing whole maps is supposed to be very easy with the new workshop.
