I don't know, this particular pocket spidey has been oddly compelling for me, I liked the backgrounds that have a kinda scaling to them, I mean buildings scrolling along gave me a sense of where my webs attach, even if only a lil bit.
I liked more control of the web powers, aimed web moves and also the moves you collect in the levels. I liked the "two animations for web-swinging" thing, its one way to keep close to its console cousins.
Overall, this product somehow feels more polished and I can't think of any compromises from the previous games at all, unlike other Spidey games I know..
