I have had this wager going for sometime now...This is my official no backing out wager. I will admit MASSIVE ownage if I am wrong...but I gotta feeling I won't be.
Halo as a series has gone from high 9's to low 7's.
Killzone as a series has gone from high 6's to medium 8's.
With the resources being poured into Killzone 2 and the experienced new devs working on it...I have faith Killzone 2 will own Halo 3.
As for the resoources in Halo 3....well let's just say I don't even think they really care...Bungie is bored of Halo...it's why this is their last one...and before the game is even retired we have the rights being sold off to noob studios..like ensemble...Halo's worst days are ahead of her while conversly Killzone's worst are behind her.
