If you've seen the new retina display, you know how games seem to degrade if there weren't any graphical updates. Stephanie Chu has been scouting the Internet for games that will blow you away in both game play AND visual goodness. See reviews for Osmos and Real Racing.
Osmos is described to feature an "addictive, physics-based gameplay, fluid multitouch controls, lush flowing visuals, and a chill soundtrack." This game will keep you absorbing matter for hours on end, or at least for the duration of your travels. The goal here is to become the dominant energy whose lifeform outlasts the rest. The 27 levels of this game are great for your travels!
Real Racing has received loads of design awards, including one from Apple who claims that this app "sets the standard for quality and console like performance and capabilities on the iPhone". PSP watch out, because this app handles great with the iPhone's accelerometer. With stellar graphics and fun game play, this app is definitely worth checking out.
