how long is AC2?

Hey guys i just got AC2 for chirstmas and i was wondering how long it is so that i can pace myself when playing. I have the first one and in that i always tend to do view points of the areaand a couple side missions firstbefore doing the mission then finishing up whatever i miseed after. I plan on doing the same with this and all the extra sidee missions and dungeons. So basically how long does it take to do everything in the game lol (cept for the feathers cause i hate doing those things). Thankshow long is AC2?
took me around 26 hrs but i did extra missions and found most of the glyphs.how long is AC2?
30 to 40 hours if you want to do all side quests, get all the achievements, and unlock everything.
Took me around 25 - 30hrs to get all the side quests, all acheivements, and hidden items.
32 hours for me. =P

Mine said like 27hrs, but then I re-loaded, and it said 14hrs, and then the next day when I reloaded it said 25hrs. So Idk how long..25 seems about right.
It's really long, and there is more than plenty to do in the game, whether you're focusing on Achievements or not. I played it for extensive periods of time for the first two of three days I started playing it, and then finally couldn't help myself and 1000/1000'ed it during a long 10-hour session.
Im confused. When i look at the DNA, does that mean each Sequence is a chapter? The game looks short then because there is more missions in sequence 1, and it looks like sequence 2 and 3 have less.
Lol, I leave my games unpaused, so the time accumulates while I eat. =P
