If I’m describing a beautiful shining steel unicorn with green eyes like beacons burning through the city’s misty night, I’m seeing it, standing in front of a skyscraper. But such illos are not necessarily easy to find. 😉
And where RPGs are involved and since anything is possible… like I said, I may really need flying pigs illos…err… in a star trek cruiser. ;P
Edit: …so for stuff like that, no illo, just feels better. 🙂
