I think this is a brilliant point for discussion.
I'd like it if each dinosaurs vocals carried different distances - reflecting how loud each dinosaur is/was. e.g. the T-Rex call should carry accross the park but the Stegasaurus call should only reach half(?) way across the park.
Each dino should have varied levels of vocals, ( quiet, loud, etc.) - lets face it, it's not like we always walking around shouting everything.
Exactly. I think we should be fine; Frontier are very good when it comes to these things.
It's little features like this that really would make it believable as a dinosaur park.
