I gotta say I'm really excited about this feature. I really hope this means the buildings and vehicles from Return to Jurassic Park are back in JWE2 as well as brand new ones based on The Lost World. I also hope these era specific items aren't restricted to the chaos theory levels they're in and, upon completion, we get to use them in the main game this time around. From a park management point of view, it's hard to imagine what scene from JP3 they could use for this mode. Kinda hoping this means there might be some new survival type of gameplay this time around. Still holding out hope that we might get to actually walk around our parks as either a guest or a worker.
