The ball would have to be about 3 times the weight, the bat would have to be about twice the weight and the bases would have to be further apart, assuming that the players were wearing highly advanced space suits that would allow enough natural movement to play.
the proportion of the earth and the moon would be much different, and the moon would then revolve on its own around the sun.
Your wight on the moon would be about one sixth of what it is on Earth.
The baseball would fall straight down towards the moon's surface due to the moon's gravitational pull. There is no atmosphere on the moon to create air resistance or drag on the falling object.
Nature would be quite different without it.
It is different in almost every game. You'll have to include which Harvest Moon game you are playing for people to answer properly.
I dont think so, because if it would chances are it would be playing now:D
most likely on the top of the of the moon Edit: To previous answer... There is no 'top of the moon'. To one side of the earth (the bottom) the top would be different then the other side of the moon (the top).
When you observe a crescent moon it is because only that crescent portion of the moon is illuminated by the sun from your particular perspective, here on Earth. If we were looking at the moon from a different angle in space, we would see different parts of the moon illuminated by the sun.
Different gravitational pull
You should specify which Harvest Moon game you are playing. But as far as I know you can not buy Bananas anywhere in any Harvest Moon game.
It would be brighter then just a moon, and tides would be different.
