Merge Plane vs Sky Force Anniversary
Merge Plane
Merge Plane is a game that's really similar, in terms of gameplay, to any other merge-based games that you may have played before. However, in this game, instead of building up a farm or a city, you'll be building an airline empire! Merge two of the same planes to discover new airplanes. The more you merge, the better planes you can get. These planes can then be send into the air to earn you some cash. Of course, you can always spend some coins to upgrade your parking apron so you can house more planes.The game itself is a really simple idle-like game that is based fundamentally on a really simple game concept. However, Merge Plane made things a whole lot interesting by providing players with plenty of beautifully-designed planes to discover and collect. This is a fun merge-based game, overall.
Sky Force Anniversary
Sky Force Anniversary brings Sky Force to platforms other than Android and iOS, namely PC and consoles, allowing even more players to enjoy its exhilarating arcade shooting action. It is basically similar to Sky Force 2014 on mobile and features everything you'd expect to find in the latter, including challenging enemies and bosses, large number of missions, weekly PvP tourneys, an in-depth airplane upgrade system along with a wide variety of planes to fly as and weapons to blast enemies into smithereens. In this version, you can also play the game cooperatively with a friend through the game's local multiplayer option.Oddly enough, despite its similarities to Sky Force 2014, Sky Force Anniversary is available on Android as well. Unfortunately, I'm pretty sure the game doesn't support cross-platform cooperative gameplay so you can't exactly play with your friend cooperatively if he is on the PC and you on your phone.
Sky Force Anniversary is the best (and only) version of Sky Force that you can get for Nintendo Wii, PlayStation (3, 4 and Vita), and Xbox Live, but if you want to play the game on your mobile, you can get either the Anniversary version (Android only) or the 2014 version.
