I am not addicted person in playing Android games but I am goint to give some feedback about Andorid games that I've played so far.
BEST ANDROID GAMES
Angry Birds
It remain the hottest game to play in mobile. Featuring a lot more depth than players initially give it credit for with continually surprises throughout 225 levels. The user interface of this game is simple but the concept of the game requires logic and skill to win the game and open the next level. It is challenging game and the players will be more exciting to defeat the current high score of each level.
Fruit Ninja
Fruit Ninja is simple with fruit flies into the air and must slice it before it falls. The player swipes across with finger. It is similar with Tetris, where you play until the game gets so difficult that you die. And it's a good one.
WordFeud
WordFeud is a multiplayer version of Scrabble, and it's a good one. The in-game dictionary is solid and the graphics are good enough. It is challenging because of its multiplayer. the player can challenge his/her friends from his/her contacts list or play a random stranger. The player quickly matched with an opponent by the notification built into the game. There are some other Scrabble-like Android games, but WordFeud is the most I've played so far.
WORST ANDROID GAMES
Alchemy Classic
Alchemy Vlassic works with four elements such as water, fire, air, and fire. The game aims to create all 188elements, by mixing the ones you already have. It really doesn't require much brain work to play it. But it is quite boring because the mixing process is informative wherein the elements will combine in another elements that results in unrealistic things like fire+water=alcohol. In other words this game shows you how to create new things that doesn't exists in reality.
Radiant HD
Radiant is topd-don space shooter. The player controls a space ship and tap left or right to move around and kill the monsters to increase points and get into the next level. However, the design and graphics does not suitable in other Android games. It is just a classic arcade game transferred in Android phones without new design of elements of the game and the speed of the space ship is slow.
Cut the Rope
Cut the ropes by simply swiping your fingers across them to deliver the candy to the little python. The rope aims to collect stars with candy as you feed the hungry python. Cut the Rope's near endless number of levels get more difficult and never put a time limit on you. But the problem is that there is no additional elements that need to destroy for additional points. So what's the point to play a game without a twist to play again the level to get new high scores.
CONCLUSION
It is important to create unique games that will appreciate of both children, teenager, and adults. The user interface has a big impact for the gamers and for me the next factors that I consider in playing Android game is the sense of the game. There is big impact for a game on what will be the effects in reality.
