Hero of Sparta
First on this list would have to be Hero of Sparta [iTunes]. It introduced something that I hadn't seen in an iPhone game yet: stunning graphics. Yes, the "pixel heaven" in this game could compare to the PSP (Playstation Portable) or rival the graphics found on the Nintendo DS. If you like RPG (Role Playing Games) games, then this is a must-have. True to the title of the game, you play a Spartan King who goes on an adventure and encounters many enemies.
While this game doesn't really use the accelerometer to control movements, it does have game play controls that are one of a kind. Hero of Sparta features an on-screen "analog" control stick that allows you to move throughout the different levels. You will use this analog stick in conjunction with action buttons; the use of on-screen buttons seems natural after a while, but may take some getting used to at first. This game features 8 3D levels with awesome graphics and 5 changeable weapons, including: sword, axe, bow, or twin blades.
Hero of Sparta works on both the iPhone and iPod touch; however, I recommend restarting your iPhone before playing as this will lessen the possibility for crashes. You can pick up this game from the iTunes App Store for $9.99US.
BurnBall [iTunes link] is a nicely designed game that gives you the sense of playing inside of a comic book-like world. Even the instructions are a comic book ... a very nice touch! The basic idea behind the game is that you must block-off 75% of each level to advance to the next level. As you tilt the iPhone left/right and up/down, Roy (the character behind burn ball) will roll around. Use him to "burn" a path through the level -- this will block off where you travel. Once you have 75% blocked off you will be able to advance to the next level. However, there are robot obstacles that, if hit, will take a life.
This game is tons of fun, and addictive. It is certainly a game that keeps me coming back for more. And for $1.99US, this game will give you hours and hours of game play for your money. BurnBall can be downloaded on the App Store. There is also a lite version [iTunes] available for free.
