I have used gamecentral UK for 18 months now via my mobile phone.
They update daily with sections such as........ Features, Newscentral, Reviews, Previews, weekly charts from the UK, USA and Japan, 4 players, Game test and Hot topic inbox where you can comment on the topic of the week (i.e. fave game ever, worse movie tie in game ect)
Today in their news section they mention a wii exclusive........ Gladiator A.D. and say theres gonna be another wii exclusive revealed later this week before E3.
Their last review that i remember becuase of my interest in the game was Virtual On O.T. for xbla and it only scored 6/10 which is also below the average score for that game.
It's a good site and i access it via a pay as you go mobile so i can't complain considering it's free.
