I personally like Stuckgamer.com for its video walkthroughs. You don't read, but watch what you have to do. Laziness at its best. =) However, for reading up on guides and games....I use IGN and Gamefaqs.
Depends on what games your lookin for and what you need. Gamefaqs is the bomb but only limited to walk throughs. RPGamer has the best overall coverage for RPG and IGN is k but too confusing to get around lol.
No, I don't even bother. I just read the articles, or the forums for new info. :laugh At least, I used to read the forums for info. Now I just check articles.
