I'm loving the DLC, but one extra option that would make it just a bit better is a third era option for challenge and sandbox modes, 'Mixed Era', that includes ALL buildings, research, and dinosaurs from both the JP and JW eras. We would need an option to either demolish the entrance monorail or choose whether or not to have one before starting the game, but other than that I see no reason why such an option can't exist. I'd REALLY like to be able to use the superior JP style without losing access to viewing galleries, and I'd similarly like to be able to use things like the dinosaur signs in a JW style park.
