Mine combines two, because I'm awkward. However, my original intention wasn't to use two Final Fantasy names at all. I was using the name 'Raine' in my comic book drawings long before Final Fantasy VIII was released, and the 'Cloud' part was added to my username in order to make 'Rain Cloud' seem a little trendier.
Most people just assume that I've taken the names from FF. But, that isn't really the case.
Interesting list, BoB.
