The artists gave me a texture for the moon in gta3. I placed the moon in the sky, made sure it was visible at night and that it was a reasonable size. A few days later 4 artists were at my desk asking me to change the size of the moon. "No problem" I said. It turned out they couldn't decide what the size of the moon should be. Two of them wanted it smaller to be more realistic. The other two wanted it larger to be more cinematic. This went on a bit and I suggested to make the size of the moon changeable in the game. This way they could decide in their own time and let me know the conclusion. Since I was working on the sniper rifle, I made it so that the moon toggled through 3 sizes (small, medium, large) as the player sniped it. The artists never got back to me so I just left it in. It was still there in SA.
