Ok you may love or hate this question, but I just finished adding a nice little shadow texture to my upcoming title, Garland's Quest and I'm sort of looking at what gets a shadow. Looking through all my objects in game I came up to the fireballs (spit from out the mouths of my cute little Red Drakes) and I had to think a moment. Should I give them a shadow when I draw them?

How many games have you seen fireballs in them? Did they have a shadow or some kind of ominous glow around them? I'm leaning towards glow after thinking about it more for obvious reasons, but it does raise an interesting topic of what gets a shadow and how to use them in your 2D games. What do you fellow developers say on this topic?
