To be fair they've given a lot of non shooting games high scores
Halo 4 70 <--Hyped Shooting Game with Generally Great Reviews
Rayman Origins 100
Sleeping Dogs 95
Persona 4 100
Gravity Rush 95
Xcom 95
DmC 95 <--- same type of game as GoW
Ni No Kuni 90
you're cherry picking too much I think they give way too many games too high scores.
I don't agree with their scores at all, though. It just seems generally bad.
