Sandbox yet? (Not creative mode the game launched with. Screw that rubbish.)
Decorations?
Carnivores don't instantly go "DERE ME OTHERS IN MY PEN! KILLLLL!" and instead go "...I'll eat it if I'm hungry."?
Carnivores act intelligently to the Gyrospheres, and attack them?
Herbivores actually form herds, instead of wandering across the other side of the map, and going "I NEED SOCIAL!!!!"?
Good sized maps.
Sandbox
Same with improvements
Same map, but there have been a number of extra options that have been added. Day/Night cycle and many tweaks for managing dinosaurs for example.
Decorations?
Nope.
There are more dinosaur skins now, while it is an improvement, that really doesn't count.
Carnivores don't instantly go eat herbivores
Check.
Yes carnivores now do not hunt when they are full on hunger. A carnivore might still occasionally kill a herbivore, but not all the time.
And carnivores will take a bite of a carcass if they are hungry, even if it's not their own kill.
Herbivores actually form herds
Check.
Not just herbivores but also other social animals like raptors form social groups that stick together and some also have an alpha that everyone else follows.
Good sized maps
No.
But there is one paid DLC that adds two new maps.
Summary
In general it's mostly the same game but improved in many areas. It's mainly the dinosaur behaviour that has improved most. But there are other improvements as well. More dinosaur skins. New type of large feeder that have a bigger supply and don't need to be resupplied as often. Visitor view from monorail, viewing buildings and hotels which is kinda neat. The challenge mode adds some replay value as well.
There are two paid DLCs right now.
- Secrets of Doctor Wu: This adds 2 new dinosaurs, Olorotitan and Troodon. The latter is venomous. It also adds 3 new hybrid dinosaurs. 2 new small maps and a story line with missions that go with it.
- Cretaceous Dinosaur pack: This is just a dinosaur pack that adds Iguanodon, Carcharodontosaurus and Dreadnoughtus.
Overall I personally think that decorations are probably what the game needs most right now. But the dinosaur management and behaviour has been nicely improved. That was kinda the focus of the game to begin with. So it's basically a better version of what it was in the beginning. But there aren't that many huge additions that really change the game in a major way.
I'm still enjoying the game in any case.
You're all saying sandbox has been "Improved" Does this mean they actually added a sandbox, or are they still falsely calling their Creative Mode a Sandbox?
Not sure what you mean by falsely calling it Sandbox. But they added a load of options like Day/Night cycle, lots of options for turning off dinosaur needs, lifespan etc. infinite feeders. That sort of thing. So it's similar but improved a lot due to the extra options.
