Kingdom Rush features quite a lengthy campaign with 12 large levels, a bunch of special challenges, boss battles, secrets and many different upgrades and playable heroes. Replay-ability is excellent.
Kingdom Rush is a tower defense game at its best, with lot of different options and gameplay features. There are many different elements you can adjust, which creates an exciting and tailored gaming experience.
Kingdom Rush has some in-app purchases to unlock new playable heroes - which is understandable considering the game is free to download. However, there are also microtransactions available in exchange for in-game currency which can be used to buy temporary power-ups.
Users are given the option to buy various amounts of coins in the game. Fortunately, these purchases are only a way to make things move along faster, and aren't necessary for the natural progression of the game.
Civilization Revolution is a 4X game in its veins, but it'll also appeal to players who are less experienced with sophisticated gameplay elements. For example, the amount of strategy that is required in Civilization is quite extensive. As a player, you constantly need to control many different aspects of the game in order to defeat your adversaries.
The classic Civilization gameplay elements and characteristics are translated well in the mobile app, with easily usable navigation elements and good controls.
Some users are reporting technical crashes and issues with the game on older devices. Thankfully, there aren't many bug reports for some newer devices starting from iOS 7.
Altough the entry price of $2,99 is quite low compared to other 4X strategy games, the developers try to make up for it with in-app purchases. The IAP's are relatively small, ranging from $0.99 to $3.99. Nonetheless, nobody likes microtransactions in a paid game.
Instead of using external sources to judge whether or not certain moves are reasonable, the game considers all factors and gives users important stats.
There's no significant first-turn or second-turn advantage in Hearthstone. The player going second gets an extra card from his deck as well as "The Coin", a card that gives one extra mana crystal for one turn. This subverts the advantage that would be gained otherwise by the player going first.
Hearthstone has a friendly learning curve that makes picking it up and getting started easy for people who don't want to spend a lot of time learning rules and tricks.
There is a bit of a grind in earning new cards, so for those that do not want to spend the large amount of time needed to earn quality cards they will need to be purchased, which can get expensive.
Users have a lot of control over weapons and use them over very long distances like in real life. Shots must be carefully calculated in order to be accurate.
