Now as I have translated and (I hope) understood all the text...
1. UE was good - when it was UE2. I have no it.
2. UNITY - must not be newer than 3.5 - has no functions that I need.
3. My preference is to learn by examples. I look on exist templates as these examples.
4. All my work - models, textures, sounds, music, scripts, so on - I do by myself. Trash content from Unity Asset Store is not interest me.
5. If my question is 'so elementary' - where is the 'so elementary' answer on my 'so elementary' question?
