I can understand your point of view very well, and I ´m happy for fans of CC that a few new Species ( 2 ) and remodels ( 2 ) + some new skins are on their way for us Players !
But the free update is this time muuuuucccccch nicer than what i get for almost 10€ with this payed DLC!
And in former DLC´s for JWE I where some realy nice new Buildings and Attractions in some of the DLC´s ....best ever was for example " return to jurassic park" ihn which we got an 2 new Atraktions ( Jurrassic Tour ....like in JP I ) and the Pterodome ( Aviary) with new hotels .... the bunker and the Raptor Pen etc. .....and comparing to this dlc is the CC very minimalistic ....that´s all I trie to say. River Ride ( with Kajaks) and Cable Car ( Transport to the Hang Glider hill ) were shown in CC in many scenes and where both on the wishlist of many players for a very long time. The Treehouse would have given much more variety for hotels in the Parks. I would gladly have paid even 15€ for the DLC if just this basic new attractions would have been in it ! The 6 Campers ( visitorskins) would have been Welcome for first person mode by many fans as well.
I hope the Dominion DLC will have a few new Attractions, because this CC DLC seems very Basic to me.
Free update is a 9/10 ( Placeable Plants/ Rocks etc for the Lagoons and it would be 10/10

!),but the CC DLC is more like 5/10 for me....but hey thats only my opinion.
