Halo 3 has 9.4 million copies sold. It got 93.3% on Gamerankings.

Killzone 2 only 1.3 million sold. It got 90.8% on Gamerankings.

Halo 3 sold 7 times as many copies as Killzone 2.

I think Halo 3 killed Killzone 2.

Using your logic...

Halo 3 didnt kill Killzone 2, as Halo 3 was already "killed" by CoD4.
