Chose Gamespot as they give balanced reviews of games. Well most of the time.
For instance when every other US game site was shoving dung on Gothic 3 and gagging over Oblivion like whores, Gamespot went against this trend. In so doing they were able to look at Gothic 3 objectively and review it accordingly.
Plus I've been a fan of their's for almost 6yrs.
They also provide very good crpg walkthroughs, like Desslocks Baldur's Gate walkthrough etc.
