Looks about like the original at 2x. Nothing really new here.
I'd beg to differ, it is noticeably crisper in this version than the original 2X zoom. There was a considerable amount of blur or dullness and loss of detail on the pixels when exposed to the sub pixel level at 2X zoom previously that you can notice has changed in this version. It is not a stark difference mind you, but it is noticable enough to tell the difference that there is no pixel loss or blur, and that the game has been enhanced by some software solution (as they obviously did not redo the graphics in double scale)! Look at the text, font, character borders, interface borders, heck pretty much everything looks cleaner than the washed out 2X zoom that gives every game a faded look! Maybe it's just the difference of running it on the new iPad but I ran the previous version on this iPad too and see it quite clearly.
