Uh..Wha..? I think we are considering two different things. This, that Luna is a party freak and passes out so we have daytime moon is now headcanon. i dont have a clue where you got video games from this.
I love to par-ty with all my friends!!!! Then I get so drunk that I cannot ower the moon to make way for the dawn..... So that's how you see a moon in the day, sometimes. WAIT! Maybe if I get drunk every night I won't have to lower the moon, and those ponies who ignore my moon can see it!!! TA-DA! Splendid....
Though, for us humans, consider this: Whether or not the moon is visible in the daytime sky is dependent on the phase of the moon. The closer the moon is to new moon, the less the "angle" between moon an sun are, until the moon is completely invisible in the daytime sky. In contrast, on the full moon, the moon can't be seen either since it's on the other side of the horizon as the sun
When you go outside during a clear day marked as a half moon (either one) on your calendar, the Moon and Sun should be at 90 degrees from one another
