I see it as Killzone 2 Vs Halo and Forza VS GT.   They are each others antithesis to each others goliaths.  So then the question remains, will Forza be more effective than Killzone or will Killzone be more effective. I personally think Kilzone 2 will sell more because it has the best graphics in the world on the most powerful system in the world and uses the full power of Blue ray and the Cell.

forza will sell more then Killzone 2.

lol you think killzone 2 will out sell forza 3 becasue it has better graphic lol ok tell my why Killzone 2 is having a hard time out selling halo wars a RTS game.

LOL did Killzone 2 even sell 2million yet.

Serious thread?

Forza 3... easily.

panasonic - did forza even sell 2 million before being bundled?

Yes it did

Forza, Killzone 2 was a sequel to an average shooter on the PS2 and has sold well, but not brilliantly.

Forza has sold 4 million (including bundles etc.), but 360 will have a larger user base in Europe (when Forza3 releases), where racing games are quite popular.

Proof? The game was bundled in two models for a good 6 months (fall and winter busiest shopping times)

Forza, easily

We are comparing sales of a shooter to racer?
