whilst i will agree with you on a personal note.

i will disagree on a objective, games are all about personal choice and taste. so whilst a game may score 10 in every review in every mag, not everyone will like it. it is also a hard level to judge, due to the reviewer, magazine, etc. it is also worth noting many games mags/sites are paid for by publishing houses or the bigger corportations.

i mean people bitch about halo all the time but that sold well. i personally love halo.

so really in the war of consoles it has to be awarded on console sales. as these give a better reflection of the market trends.

on a personal note i would only say there have been 4 great games this year for 360. those being halo, bioshock, cod 4, mass effect(although riddled with bugs) but these are only my opinon.
There are also shit hot games on wii, rs4, wii sports, zelda cross bow training, emergency hospital, mario galaxy.

but it is all a matter of taste.

so consoles has to be the clear decider in winner.
