i havent played killzone 3, but i can tell you, cod modern warfare is a great game.
Modern Warfare 2 is better. It has improved guns and better graphics. It was also better promoted than Modern Warfare 1.
in my opinion,modern warfare 2 multiplayer is way better,better graphics,spec ops ,and more ranks to show off
It's all up to your personal preferance but I prefer the modern warfare 2 maps
Modern Warfare Mobilized(the DS port of Modern Warfare 1) & Modern Warfare 3.
This is completely subjective and a matter of opinion, however my opinion would be that they're both good quality games. They both have their own advantages, modern warfare 2 has much better perks and more personalisation, however modern warfare 1 has better maps and better guns, overall i'd say only you can answer the question, but my experience would say COD 4
Modern warfare 1 or 2?
Killzone 1 is, Killzone 2 is not and Killzone 3 is.
yes there is in my opinion it is better than mw2 mulitplayer
Get Modern Warfare 2.
no killzone 1 is one ps2 the killzone retribution is on psp tho
2 players in campaign are better.
I would say that Call of Duty: Modern Warfare 2 is better, because of the weapon selection, perk selection, graphics, gameplay - both multiplayer and singleplayer storyline, the killstreak reward selection, the offline multiplayer class customization feature, and the online multiplayer gameplay. Everything about Modern Warfare 2 is better. Except the price.
