If I had a goal, it would probably be to have one of each type/gender. But really, I think I've already got that, other than discontinued types, so it doesn't matter.
So my goal now is just to have a lot of pretty dragons, and that's about it. I tend to have armies of various kinds of purple dragons (purple nebulae, horse, dream, mountain, etc.), just because I like purple, and when I see an egg from one of them on the AP, I usually snag it.
I didn't win anything, but I've never won anything in a non-skill-based contest in my entire life, so that was no surprise to me.
Remember, though, that if any of the winners doesn't reply to TJ, he has a second list of people that might get a prize. So someone here COULD get a prize! And if they do, I want to be in line for a child!
