I would disagree with that. Multiplayer is very good in KZ3. The reason it doesn't sell as well as Halo or Gears is because it the hype machine isn't their for it. Xbox owners are quick to pick up any crap game which is why most games sell more on the 360 vs. the PS3. PS3 fans are generally more select in their purchases. For me, I don't like any of the Halo games, none of the Gears games and none of the Call of Duty games.Resident Evil was also a horrible game. To me the controls were crap and the overall gameplay wasn't fun. Same goes for Socom series on PS3 Unreal Tournament etc. Really the only good FPS on the PS3 are KZ and Resistance. Warhawk and Uncharted take the crown for 3rd person. I still play KZ2, Warhawk, KZ3 and Uncharted 2 online. 

I deleted my post, but since you're going on, there's a difference between having a discussion and rubbing someone's nose in it. I don't know what to say to you if you think a post like "Your continuous hostility to a small error only shows that you have a hard time with discussions that don't go your way." either will provoke a positive response or not make you sound like you have an incredibly holier than thou attitude.

Well since according to the OP it should atleast sell on God of war level(3m) then I think with its current legs plus holiday boost it shouldn't be much of a problem reaching that.

My aggression comes from the fact that there's no middleground in this argument. Apparently you either think Killzone 3 sold great or you think it sold disappointingly because it didn't sell like Halo. This thread doesn't reflect that someone might think it's disappointing, but doesn't think it should sell like Halo. Instead we have the same "why Killzone doesn't sell like Halo" conversation that we've had a gizillion times before.

Why would one expect huge sales out of the Killzone franchise?  Killzone had to overcome a bunch of negative stigma it has prior to Killzone 2, and also the entire E3 trailer fiasco.  It turned out real good, however, which offset a bunch of things.  But, also needed to factor in that the FPS genre is saturated at this point.  What one hopes for is that a FPS franchise gets a sufficiently large following that it can continue to produce sequels, and make the company who owns the IP a profit.  But in a saturated market that is established, you won't get much movement away from the established brands, unless someone drops the ball.

kz3 has more than just rank bonuses, in game ribbons, exoskelotons, jetpacks, missions etc etc....I'm not gonna get into this sale argument tbh...if it sells well not halo well but well, then I have no complaints whatsoever...there are plenty of ppl to play with online all the time so my experience has been nothing but awesome. I just wanted to point out what you said absolutely made no sense and to be frank..a lie. Let's just leave it at that..

Halo isn't even Halo any longer.  The market is full of FPS at this point, that you end up with Call of Duty stealing the thunder.  Halo is a flagship and iconic franchise the way Gran Turismo is.  But hard to suddenly thing a title late in the games as Killzone is, would suddently do Halo numbers.

You are so right about that

From my experience with Killzone 2, Resistance, and Lost Planet multiplayer is that these games appeal to a smaller audience, and gameplay isn't as balanced, or applicable as Call of Duty or Halo. I mean in Lost Planet for example, get in a VS and you're on a kill streak, and the concept of using a grapple to climb is unusual.

When I say less addictive multiplayer, I'm probably using a poor choice of vocabulary. With my first point, I mean to say that the multiplayer keeps less people in. With the second point, I mean to say it draws less people in.

I don't think the second point is debatable. For the exact same reasons battlefield see's 1/4th as many sales as a CoD title. It's not THE multiplayer game to play, so it's brushed aside by most because a lot of gamers dedicate themselves to one game franchise

That bold comment I think is extremely biased. FPS sell better on 360 for the simple reason that there are 5:3 360's to PS3's in Americas, and Americas is about (2/3) to (4/5) the FPS market (depending the the game). Look at Call of Duty and Halo, and you will see most sales are in Americas despite PS3 having roughly the same sized market in EMEAA. The only time a 360 FPS sells more then 40% a PS3 FPS is when the 360 version is advertized more, as in the case of Homefront.

As for preferences, everyone has their own. I'm a big Lost Planet 1 fan(Not 2, 2 way terrible), but it never sold that well, even as an exclusive (timed, but who knew when it came out?). Halo, CoD, and Gears sell well because A. They are actually great polished games which get very high reviews, B. They appeal to the masses, similar to Mario Kart.

Killzone desrves more sales, but with 3 exclusive shooters to balance on the PS3, all relatively new franchises, and a much smaller instal base in the Americas region, I can see why sales are slow.

BTW for me, I tend to play almost every online game I can get my hands on, even if the experience is only par. I mostly play online, and I burn through all the online achievements/trophies relatively quickly. Only time I stop playing online for a game is when matchmaking takes a long time, and has unbalanced matched. That's why I stopped playing Front Mission online. When I get Crysis 2, I'll play it online, even though the MP demo kind of sucked. I'm currently only playing Halo and CoD online, but craving a new experience.

P.S. I find it funny to always see CGI in an arguement..

Well lets just say it's not hyped as much for casual gamers as Halo or CoD. I think not being the star title in a fall lineup makes a big difference to overall sales.
