I also love Web of Shadows and I play it from time to time. In my opinion WoS had the potential to be the BEST SPIDER-MAN GAME OF ALL TIME. Great controls, decent graphic style and a huge city. If they just included the side missions, multiple story lines and day-night-cycle which made Spider-Man 2 so great it would be my favorite Spider-Man game.
The game was pretty good in structure, it just REALLY needed to be ironed out. I should also point out that there WAS a sequel in development at some point before it got canned.
