People do realize that scores are all over the place for another recently released open-world game, right? What I really don't understand is why people feel the need to force their opinions down other readers throats. Its cool to state your opinion, and if you don't like it, great. But if someone attacks you for it, hanging around and just continuing to attack back makes you just as bad. People need to learn to take the high road every once and awhile, it'd make the internets a much better place.
With that said, I'd like to touch on something that I have seen brought up, that being the city not being as "pretty" or "organic" as 'that other game.' Sure it is not the best graphically, but what each game does a good job of is working to the benefit of the locomotion of the player through the environment. In 'that other game' the city is built for climbing and shooting from the sides of buildings, etc. In Prototype, the city is there to run up and move through very swiftly. Could it look a bit better? Sure, but it gets the job done.
I will say that a 5.5 in graphics seems a bit on the low side, but I'm more apt to notice things like a stoplight that has cars behind it, like 20 of them, and they all are taxis. I'm not a huge graphics whore, but things like that make me giggle.
I've only played for about two hours, and the best I can say for comparing the two games is this: One is a great game in which through the course of the narrative you become the ultimate badass, the other is a good game in which you can probably quickly get every and just be the ultimate badass. Both are fun, you'll likely find one slightly more enjoyable than the other, but won't loose with picking up either.
