New Super Mario Bros 2 vs Sky Force Anniversary
New Super Mario Bros 2
New Super Mario Bros 2 provides you with another exciting Super Mario adventure to embark on to save the hapless Princess Peach from Bowser! This time around though, the Mushroom Kingdom has a lot more gold coins for Mario to collect - and he needs to collect as many as he can - in addition to simply completing a level. There are also special power-ups that can turn everything in Mario's path in coins. Aside from the usual 2-player multiplayer mode, the game now has a new Coin Rush mode where players will rush through 3 levels while collecting as many coins as they can and then challenge their friends to do the same. With the return of Raccoon Mario, Mario can even fly and access hidden places around the game.New Super Mario Bros 2 is an incredibly fun game - more so than the previous version, that's for sure. So, if you can afford it, you should definitely buy this game.
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.
