There's a great new game out for the iPhone/iPod Touch called Hector: Badge of Carnage. You can hop over to Touch Arcade for a review of the game. I'm a big fan of adventure games in the style of the good old SCUMM games from Lucasarts. The style is more flash animation than pixel art, but it's funny and very entertaining to play. A must have like Beneath a Steel Sky and Monkey Island!
