The campaign could have been better, but when it comes to the multiplayer, they did a pretty good job on that. There are some annoyances with things like shotguns and such, but I've been playing the multiplayer since the beta and I've enjoyed it.

Personally I think the campagin isn't one of the best. For me the game still has the better graphics this generation, simply unparaleled in terms of postp-processing, shading and lighting (Uncharted 2 and ME2 have better textures still).

I enjoyed the game enough that I will probably buy the 1st one at gamestop next time I go there and the sequel when it releases
I beat KZ2 three times got all the single player trophies but have never played online

Happy with the game quality? HEK YEH!

Happy with sales? not so much but Im not entirely sad at 2.20m either.

I've spent more than 100 hours with it... so yes I'm happy with it.

Great campaign and multiplayer. Little things do drag it down though so that I only play it with friends ie: full games are a laggy mess, some balance issues.

Bit disappointing to see that only 20000 or so player played it in a day last time I played (near the 24hr daily rank reset)

I enjoyed it and I think its the best FPS online of this gen. The real classes and real clans were a refresher from Modern Warfare. They could have had more guns and the story on the campaign could have been stronger but an overall great game that could have used a few tweaks

I have played this game more than I have any other online game. It replaced warhawk as my most played multi-player so far. I have no complaints and have bought all the DLC.

Meh I shouldn't have bought it at launch....

Graphics are great, singleplayer is pretty boring and short. I think the graphics and the 40€ I paid for it were the only reasons I even finished the campaign.
Controls suck big time and that's because EVERY other shooter on any platform is much smoother. I heard the controls are more realistic, but "realism" doesn't automatically mean "better".
Multiplayer is great, though I'm not very interested in that part of the game.

in KZ2 i see myself spending more time in multiplayer rather than concentrating on the campaign. Controls in KZ2, i have to admit its kind of bad and seems it lacks the fluidity in the movement. Funny thing its quite difficult to make a simple 180 turn or even a 360 and at times of near death the stress can get to you.
like Wagram said it may take a learning curve to properly learn the controls.........
