I'm writing space combat examples for Icar at the moment and good grief is it ever dull! I'm going to spice it up with pictures but the act of writing down what is going on word for word is very boring.
Sadly, they are absolutely neccessary. If you want to get people to play your game, examples are a must. When I read other people's games, I find the examples enlightening (oh, that's what they mean) in support of the rules.
I empathise with all RPG author that leave them out - they're not very interesting to make!
