Unity5games has released a demo of a scene they created from Jurassic Park with the Unity engine:

Players can enter and exit the car, choosing to walk around the area while the T-Rex breaks out and walks around the area itself. 

You can find the demo here: https://unity5games.itch.io/t-rex-breakout-free-dinosaur-game

I think it's pretty damn good looking for Unity, though it has obvious performance sisues, even for a demo. 

It'd be nice to see a new Jurassic park FPS or third person game (non VR based).

This guys need to do an actual game, just to show what the engine is capable of. Just like when EPIC did Unreal Tournament or Gears.

He should, but we know how it would go with movie licenses. He'd likely have to ask permission from Universal Pictures if they are allowed to user their IP for a game. That and they'd need a 3rd party publisher as well as some backing and a bigger team.

Still, this is just a demo and it managed to scare me pretty good. The car's interior was rather shoddy, but the rain, sound and dinosaur skin looked the part.

I am not talking about Jurasic Park, I am talking about in general about all the demos the Unity Engine has.   They even have Animation short series in youtube like ADAM, among others.  

They have to do an actual game.

Well you did say "this guys", meaning these guys. They could very well make a game, and gathering from the Demo, they seem quite interested in a JP game. 

They don't have to force their hand to make a game though, as that's up to them. 

Besides, there are people out there making games that use the Unity engine anyway. 

Hey, I heard it's so good!

Hey, it got me pretty ruffled.

I got out of the car, the Rex was coming my way, so I got back in and eventually become canned tuna.

9/10, immersive and scary af. 

yes, but none look as impressive as ADAM series.   The makers of the engine should show what their engine is capable of doing when you use it "adequately", in an actual game.

Everyone can make tech demos, but to actually having an impressive looking game is a very different thing.

because the Adam series has been designed to work as a short story, and not an actual video game.

To use it as well as they do, you'd have to be on their level of knowledge and have a lot of money, not to mention an idea for what could be a good looking and good playing game. 

It still hasn't stopped me from appreciating what these guys have done with just a demo though. 

Well there are other youtube vids out there showing off the demo. Either that or you could download and try it out for yourself.
