I was horrible online ! i assumed it would be as easy and fun as halo3 online

No game is like Halo 3 online. The closest you'll get is Unreal Tournament III, and even that's pretty far.

KZ2 is pretty similar to CoD4, actually.

OT: Well, the sales figures are as of 8th March, while the online figures would be 14th March. I would expect it to be at around 1.2 million by now, but 50% is still not bad.

So was I.  Now I'm in the top 15,000 and I don't even play too much to be honest. 

It's one of those games with a steeper learning curve but once you get past the learning curve.  It's a blast with tons of extra unlockables.    I'm at a point where I'm very comfortable with the controls and can use pretty much any gun and aim how I want to now.      Tons of fun.    You just have to put a few hours into it to get more comfortable.

well since he returned the game it doesent really matter.. but those people are actually right... as you can see from my posting history im not as ...enthusiastic about the game as many others are.. still im having quite a blast online

at first i was really pissed that everyone else was like "its not the controlls its your aiming" "just wait till you unlock the other classes" "the mp is really fun and diverse" and i was like what? all i get is grenade spamming idiots who use the shotgun as soon as they unlock it .later there are also the idiots with the rocket launchers

but those people who say take your time , are actualy right.. you just need to invest some time into the way it works.. at first there may be a lot of people with no skill who kick your ass and you feel like you will never be any good at it..but the cowardous "tactics" they use get less and less effective while your aim and your knowledge of each map increases

now im actually far enough to kick those peoples asses ..just plant some c4 or use the sniper with the spot target ability and the improved scope and watch them die

tl:dr its no use since you returned the game but after a while even a console shooter amateur like me who sucks royal ass can can be a succesfulll saboteur sniper or anything else that involes more than "select shotgun ,walk into 2metres range of target, press R1 ,repeat"

It is not as accurate as we can get, and it is not justifyable to say 'Oh we cocked up somewhere else so we can put bogus numbers here too'

As ameratsu stated, a single sold copy of K2 can have many online accounts associated with it. Siblings will probably each have one, and when people sell the game 2nd hand it adds to this problem by creating more accounts without extra sales

Further more, a rented copy of K2 will have many accounts associated with it, and yet is not tracked as even a single sale by VGChartz I believe

And yes, those things are unavoidable, but that does not allow you to present this data as the truth, especially not when you consider the biggest flaw with this data.

VGChartz presents data weekly, these numbers are from the 13th. Meaning that there will be many people who have bought the game and played online, but are not included in VGChartz's 1 million figure. If someone with a PS3 could find out the number of accounts on the 14th, then we can compare it to VGC sales from the 14th, to give us a slightly less wildly innacurate number
