Well, it has some PoE themed "maps" (as much as I know just random locations with stronger mobs, didn't impress me at all when I was lurking random PoD streams), rebalanced skills and charm system. You have large inventory, but charms work only in particular section of it. If charm is located outside of that area, it has some absurd level req. I'd even consider trying it out if there was no annihilus patch&reset coming that soon.
