This is your definition of a balanced game. I have another. Another person has something different. So you see that you can't really say that a balanced games has..... as this is not a fact but only an opinion.

Anyway i agrre on 1).
I do care for 2) but i don't find it necessary for a balanced game.
As for the 3) it's wrong. How do you know that at Chess or Gothic Chess white or black hasn't a definite advantage at move 1? If you mean "obvious" advantage then i think that at Bird's variation this is not true.
I don't think 4) has nothing to do with a well-balanced game.
