I'm looking into purchasing a few games for my iPad. Most of the games I'm considering have both an iPhone and iPad version, and in most cases the price difference is big: Plants vs. Zombies, for example costs $9.99 for the HD version and only $2.99 for the iPhone version. The iPhone games I've scaled up on my iPad don't look terrible, but obviously the picture difference can be glaring in many cases. However, I watched a YouTube video this afternoon reviewing the two Plants vs. Zombies versions, and the scaled iPhone version didn't look too dissimilar to the iPad version. Unfortunately there aren't many other videos comparing iPhone vs. iPad apps, which would be really nice. Anyway, I'm wondering if you all have found that the higher price is worth paying for HD apps, or perhaps that the cheaper iPhone version would have been the better bet. A few apps that I'm considering buying are PvZ, Asphalt 5, and Flight Control, all of which have less expensive iPhone versions available.
