Between the PSBlog, Kotaku and Destructoid, i'm all set.
What sites do you frequent for gaming reviews, walkthroughs, codes/cheats, upcoming release information, how-to's?
For reviews www.gamerankings.com (look at average score and then read into any that give super high (or low) ratings in-depth to see if they are valid or not).
cheats walkthroughs... I just use google search I haven't found a one stop shop.
