if possible also add achievements page which give us reward upon completion, lot of things can be added in that like having more dragons (otherwise i don't see much imp of breeding and having each and every dragon)
Until achievements are added, i feel the motivation to collect as many dragons as possible is so they get you more gold and gems, and to fill up the book
Hello! Today I have added a new feature that rewards you for collecting many dragons, it's called Collections, it gives many rewards such as Gold, Food and lots of Gems, the feature can be seen in the Dragon Book
