Is good but.

Is there any place where I could learn how to use this Engine cause all I can Find is for the 3 and I get stucked on every tutorial or I follow and it's very frustrating and I'm using this cause it seems to be the best when it comes to open spaces and the kind of game that I'm trying to do is tighly related to my nick but i don't like the fact that I cannot be learned not even from books.

Are there alternatives.

Unity, Unreal Engine is open source from my understanding. You give no requirements, but I'll assume C++? There are tons of open source C++ engines out there.

Not sure what you've found but:

I worked on CryEngine a tiny bit. We are expecting that Crytek GmbH will be shutting down soon, ending any possibility for upgrades or support, and possibly causing existing resources to be removed.

You would be better off spending your time on Unreal Engine or Unity.

If you like CryEngine, go to lumberyard then, it's basically what CryEngine will never be, you would lost too much staying with CryEngine instead of moving to Lumberyard.
And like L. Spiro said, Crytek is basically dead.
