If anyone is interested in pet games (and dragons), you might want to give Flight Rising a try! It's free to play and pretty fun. There are lots of different dragon breeds and genes, plus you can dress up your dragons in snazzy outfits.
This game does NOT allow you to register any time. You have to wait for an open registration period (to spare the servers or something?). So if you're interested I recommend jumping in.

Oh, and the first dragon you create is the only one you get to PICK the colors on. So pick wisely.
