FR is basically just selling babies. They're gonna have more up soon but its new. The economy is kinda messed up now cause theres soo many dragons but no new users balancing out and buying the cheaper ones. Imperial breeding is the best way to make money from what I've done so far. I guess the other big aspect of the game is Dominance. Each week they count up how many dragons have been 'exalted' by each flight (user group aligned by elements) and battles for dominance can be pretty heated and exciting.
