I like the Dragon Tycoon idea. I was thinking about something where you breed Dinosaurs. I like the horse idea, but it'd be neat if there was one where you could make Mythological creatures.... such as dragons, unicorns, pegasus, etc... You could breed a unicorn with a pegasus and get a flying unicorn. hehe. There could be all different kinds of unis and pegs and we could have to find the magical ones or something.

I also like the World Tycoon idea and the VV in Space idea. What about Alien Tycoon where you could breed different types of alien creatures together to find the magical ones or something?

BTW, what is Moon Tycoon? I've never heard of that one.
