Where to begin? For starters, when compared to other similar games, Dragon Story makes every in-game purchase much more expensive. For example it takes more to feed each dragon, and food is more expensive. There is also little reward for in-game achievements. Games like Dragonvale and Creatures of Olympus are much more rewarding and have balanced economies. The result is that Dragon Story requires more in-app purchases using real money in order to be remotely as enjoyable.
That, however, is not the worst of it. My account experienced glitches which removed entire habitats, including the dragons within them. Time and energy wasted. I emailed the support team, and not only did it take them several days to reply, but they were not helpful at all. The same day as their reply, I logged in only to discover that my entire island had been wiped clean, and my account reduced to level one. At this point, support couldn't even right the situation if they were willing, because I can't possibly remember all the habitats, and dragons, and what level they each were. This is the most epic of failures from a game company that I have experienced.
I have since deleted Dragon Story from my device, and will NEVER support any TeamLava or Storm8 release. Play Dragonvale; there's a lot more you can do in that game anyway.
@tangelathacker no, this is only for android and apple. the android app is missing a lot of the perks you get on your iphone or ipad or ipod.
