I do not mind to pay to upgrade to continue playing but 3 dragon spaces is not enough. I still have dragons to hatch, dragons that are not on their habitats because I couldn't buy and place the last several, so those dragons are crammed where I could fit and now there is new dragons and cannot buy the new 5 dragon habitat either because no land. Maybe if they made them all upgradable, or half or anything better than 3 I could do something
