10 hours for a FPS is becoming the norm. I would really like to see a development team get decent story lines in FPS and extend the time. CoD WaW was an incoherent mess once you got past the basic gameplay

Ten hours sounds good to me; more along the lines of what games used to be. I've been getting rather sick of games getting shorter and shorter (COD 4/5 and Gears of War, I'm looking at you) so that you can complete them on a Saturday afternoon in one sitting even if you take it slowly. That's ridiculously short for something that costs $60.

I think they just explore less. I beat the game in 6:40 on easy and 7:24 on normal, with most of hard done in a time that would put me in line with the other times.  Now i'm not very good at R2 but i never really walked around and just went from point A-B.

Nice nothing wrong with that!!!!!!!

10 hours will end up becoming 15-20+ for me just like how I liked getting lost in Rapture and Bioshock lasted 30+ for me.

Multiplayer looks awesome and can't wait to try it. I am also excited for bot support as well.

I think this game has a chance at being my favorite shooter since UTIII. Only problem is that I play UT3 with the PC Speed mod, so this game is going to feel like I am playing in slow motion.

im staight with 10 hrs i really just go for the Online .

I doubt itll be 10 hours. This is PR. probably 2/3 or max 3/4 of that, unless your really slow.

10 hours is great but now the question is what kind of 10 hours will it be? Will it be great in the beginning and middle, but by the end feel like it was dragged on? Or is it going to be 10 hours with the beginning starting off slow, middle being decent and a good/great ending. If all 10 hours is of top quality, then a contender for GOTY may be in the cards for KZ2.

Ten hours is actually far above the average FPS campaign length, and this is probably on Normal. Take this with a grain of salt, though, could be exaggerated.

Hell, though, even eight hours for an online FPS is good in this day and age. It'll probably be very high quality, and quality > quantity, right?

hundreds of hours of multipayer fun were already had in the beta...I would buy this game if it had no single player.
