Boom Space vs DragonVale
Boom Space
Boom Space is a Spin-the-Wheel game that is similar to games like Pirate Kings or more accurately, Piggy Boom. The game features adorable graphics that help it stand out from among the other games within the same genre, and not to mention, unlike other games that will have you building up islands, this game lets you build planets instead. However, the gameplay is still pretty much the same as what you'd expect from such a game - you'll essentially be spinning a wheel in hopes of getting an action - to attack a player's planet or to shield your own - or a freebie, be it free spins or coins.Like Shark Boom and Piggy Boom, you can collect pets in this game but unlike the latter, your pets can't defend your island. They are simply there for show.
So, in many ways, I'd say Boom Space is more like Shark Boom in terms of its graphics and features than Piggy Boom, Greedy Gods or Pirate Kings. However, the gameplay for all these games are basically the same, so if you enjoy playing one of these games, you'll enjoy playing the others.
DragonVale
DragonVale is a fun fantasy-themed simulation game that allows you to build your very own dragon park. Aside from the building aspect, the game is quite similar to most pet collection games since you'll be able to breed and hatch over 250 different types of dragons. You'll also have a Dragonarium (it's something like a PokeDex) to help you keep track of your collection.Interestingly, the dragons in this game is not just for show either. You can grow your dragons and enter them in fun races, quests and various competitions to win fantastic prizes. The game is even a rather social one because you can not only visit your friends' parks, give each other gifts but also set up both of your dragons for some cooperative breeding.
If you enjoy pet collection games that are a bit more casual, then you'll love DragonVale. The game is available on both Android and iOS devices.
