I have been playing this on hard mode the last few days and it's just great!
I honestly think it's my favourite since Spidey on the Playstation.
Although I do love the free roam games, this one is a nice middle ground. Don't get me wrong, it isn't Arkham, that's for sure, but it is the most complete and well-rounded Spidey game, I've played, in a long time, and most of the levels are just awesome fun. The repetition isn't as noticeable either when I'm playing it this time, probably because I'm not playing the whole thing in one go and just playing a level or two here and there.
By the way, does anyone know if the cosmic costumes were released as a download on PSN in the UK? I can't seem to find them...
