I read the thread, and you said "When was the last time a hack and slash ever won GOTY" and I said, god of war in 2005, and god of war II GOTY PS2 in 2007.
I don't believe GOW III will win GOTY (even though its F'ing amazing, but MASS EFFECT 2 clearly has gotten better reviews, and may be the better game) but I did say that it was already said that it definitely is a contender by reviews for which you said no game other than ME or AW have been called "GOTY contenders".
