inFAMOUS hits the mark as a videogame and a comic book game, despite not being based on a comic book.
The gameplay is great. You hold L1 and shoot with R1, and not with a gun but with electric bursts ala Sith Lord. As you progress through the game you learn more and more powers, which gives you use of more of the face buttons that make Cole stronger and stronger. And cooler.
Each time you gain access to a new power, your sent underground through the sewers, basically serving as a tutorial level for learning how to use that new power. You'd think it would get repetitive...but it doesn't.
Cole uses a parkour-inspired style to get around the city, while also utilizing his electrice powers to slide or skate his way on power cables or train tracks. It's very Assassins Creed-esque in how Cole climbs up buildings to get around Empire City.
Story wise, the game is also great. It plays out like a modern day superhero origin story, with a PG-13 edge to it. The cutscenes are split between playing out during in-game when Cole is in the moment and then cutting to a graphic novel drawn ctuscene with voice overs by Cole getting the story across. It works, and it's cool to look at. The music of the game is done by Amon Tobin, who also did the music for Splinter Cell Chaos Theory, and serves to be almost like Hanz Zimmer's soundtrack for Batman Begins or The Dark Knight. Very subtle, never over the top, and very atmospheric.
I've had fun with the game and still am. It's a fun, cool, graphic novel-styled game worth atleast trying out. I'd say worth picking up.
