the only reviews that i read from any online press are those from Vandal.net.. a spanish game focussed website with a very profesional view of how a review should be.. They review every aspect of the title and ussually are 3 and more pages of text for any game... are exhaustive and informative wich gives a sense of objetiveness, really a pleasure to read, and they allow users to rate the games and You can see Editor'snote and User's average note. On vita titles ALWAYS user's are far above Editors, and they give very high notes to vita titles compared to others like IGN, EDGE, gamespot and RUNA (xD)..
I used to read IGN's but they don't make sense to me anymore since that comaprative between SFIV and Blazblue some years ago...
