For those with 2nd gen: Rimelands: COMPATIBLE Aralon: Compatible, but will crash more than newer devices Pocket RPG: Not sure, I was under the impression it was incompatible but it doesn't say anything in the app description
Just gave it a whir on ipod touch 3rd gen, iOS 5. No issues at all. Sharp visuals, good framerate. Controls work perfectly. You can play it with one hand. And by the way, touch controls are the only practical option possible. Tilting is too hard to try and control.
