Casual Game - The advantage of creating it...

Hallo, I have been creating casual games and since I don't want to wait till there are enough people, I start the game and then leave- if I play a move the game goes on to the second turn.
I wait till enough people have joined and then play my move. But I think all the other players who instant join get reinforcements only in the second turn. So the player who creates the game has an advantage. Am I right ?
So what - should I wait and create units only in the second turn too ? Is this part of the casual games etiquette ? If it isn't , it should be...

Usually I don't see the creator doing that, I only openned a casual game once and I didn't wait... Also, other players get extra reinforcement on the turn 2 so it is kind of balanced
