I´m no predator, so I can´t say for sure which one to ask.

But if you want to do such a big project, you should be able to determine the right contact person.

But try 20th insteat of 30th, because otherwise you won´t get an answer.
If you aim for a clone, you should everything and even more about predator.
This mistake (30th <-> 20th) should give you some food for deep thoughts.



Against this background it was even plain awkward.
You´ll have to _be_ a predator, otherwise your attempt won´t work.

I can perfectly understand clones.
You don´t have to worry about gameplay, story, etc...
It´s all there, as reference.
Why not?
But don´t underestimate the amount of the needed investigation.

And be aware that it doesn´t matter if it´s commercial or not.
You´ll need the copyright.
