quite a few games.
Forums are need to stay on topic so less chit chat like here.
There are some npc based games/activities (pinkerton;s pile and the alchemist are where I sit at lol) in the trading post.
You could become addicted to buying dragons that people auction off, or become addicted to breeding and auctioning your own off(that's me right there, this one)
And you can always participate on dominance, in which you would exalt your dragons to serve the flight you chose, and try to get your flight to win for the week, giving your whole flight added bonuses.
