ivory echo
I find the Black Market to not even be worth building. I never use it to get new dinosaurs and I can't sell my dinosaurs on the black market(it is a marketplace this makes no sense to me) so it is a pointless structure for me to unlock.
A big problem with this game is if you get dinosaurs that you no longer want unless you want to stave them to death it is extremely difficult to do anything with them in the campaign. Too many dinosaurs won't let you rewild them, this is a problem.
I will be honest the campaign is great with this exception. For me, this breaks the immersion in the game and ruins the campaign for me. If a dinosaur breeds enough then they become unhappy and I can't rewild the dinosaur or sell it then what? This scenario happens and it hurts my ratings in the park and there really isn't anything that I can do to fix it.
