Eli, Blake and I have been trying out nearly all of the HD versions of existing iPhone games over the weekend to see how they fared on the iPad. Overall, I'd say we were very impressed with iPad gaming as an experience. The larger screen size really does add a lot of immersion to practically every game we've tried. Enough that if you are an iPad owner, as a rule, you are going to want to buy the HD version of new games going forward. While pixel-doubling of existing games works reasonably well, they simply don't live up to the experience of playing a native full-resolution version. Beyond the obvious graphical improvements, in many instances, developers have made adjustments to on-screen controls to accommodate usage patterns on the iPad.
