It would be impossible to crate an island without limits. Even if they did do this Xbox and PS4 players would suffer greatly as they are not as powerful as a PC.
Also please refrain from caps as it can come off as yelling and can be very inappropriate.
yeah I would like something like that but unfortunately not even a console could do it maybe the next gen console but not the current consoles even like an Xbox One X wouldn't have that much power to sustain the game.they could add that feature and it's sequel if Universal decided to allow Frontier to create Jurassic world Evolution to but so far in this game no.
I suggested a while back that there should be 6 locations in sandbox mode on Nublar a while back that would be far more easier to implement into the game without and it would be far better so it won't crash the game
1. 2 large Sized maps
2. 2 Medium Sized maps
3. 2 Small sized Maps- including the Current Sandbox
With new dinosaurs constantly put into the game you have to have bigger sandbox maps however a full island may be impossible for this game so I'm sorry my friend but it's not possible like I said possibly the sequel will probably have it but not this game because this game.
Would love to see a custom built Island, however I agree with most comments... I personally can't see it happening though I do agree with Alan... It would be great to build all over Nublar, but to customize it, we would need the ability to build proper rivers, lakes and mountains, cliffs and more in depth forestry ect, so basically give us full access to Nublar and give us many more tools to work with.
