Neversoft struck gold. Again.
A) Were good games, like Separation Anxiety or the Arcade game, but at the cost of being a bit more... 'generic' when it came to mechanics, only using the most basic of Spider-man's abilities.
B) Were Spider-man games, like Spider-man and X-men or Spider-man VS the Sinister 6, which were built around Spider-man's unique abilities... but weren't good games.
Spider-man on the Playstation manages to be both a fantastic game and an Spider-man game. Like, Spider-man's got so many abilities, and they are simple to get the hang of. I've gotten up to the helicopter raid escape and I've been having a blast. I have very fond memories of Spider-man 2 - Enter Electro, so it'll be interesting to see which game has aged better.
As to why I started Spider-man? I'm 10 hours into Shadow Hearts 3 so I decided to take a little break from all the turn based battles, plus, I'm running out of space on my Spider-manathon shelf, so might as well start now!
