The best reviewed PSP game on Metacritic is God of War at a 91, on the DS Chrono Trigger just edged out Mario Kart, the game’s scores are 94 and 91 respectively. The GBA’s highest rated game is Link to the Past at 95.
On the console side the top reviewed games are the Grand Theft Autos, Halos, Marios and Zeldas, spanning from 95 to 99. Console game scores for the top games seem to be significantly higher and the high ranking handheld games are either console franchises or direct ports of console games.
So what is going on here?
There are two possible explanations I can think of. Handheld games could actually be worse than console games. This may be true to someone subjectively, but it seems an absurd position for professional reviewers to adopt. → All I want for Christmas is my PSP.
