Free game engine?

Question

Game development

I am writing server-client applications. I decided to try myself in a new field, purely for the soul.
Try to write a game, but after searching on search engines, I was a little upset. All engines are either paid, or the content for them is paid.
Please tell me a good engine (preferably a link to the site), preferably 3D on which I can make a good game with beautiful graphics. (I can draw beautifully)
Main parameters:
1. Absolutely free engine and content.
2. Easy to use.
3. There is either Russian documentation or a Russian community (very desirable).

Answer 1
