Around 31 hours.  I just did the main quest and completed the DLC's.  I won't be going through the side quests until Mothership Zeta is released and completed.

Around 160 hours.

Around 20 so far, I think. I got it when it first came out, but stopped playing after around 15 hours because I was bored and frustrated. I started playing it again a week or two ago though, and now I'm starting to warm up to it.

About 10, which is way too long in my book. Game didn't do it for me.

ive only put about 10 hours. my freind has like  300 hours

I've played through the main campaign twice and finished with all the DLC ...so about 100 hours.  This has been the most immersive game this gen.

If you count the times I've had to start over because I loaded a wrong save and didn't realize, I'd say about 90-100 hours.

" about 13 hours, got bored, traded it in, never bothered to finish it. what a bore. "

" Just 20 hours. But I'm waiting for the DLC to come to PS3 so I can play it all over again. "

I am 105 hours or more. Completed all DLC, and most quests. My first character though.

Around 250+ hours across 3 characters. And I'm nowhere near done with it.

57 with my main and about 7 with my sniper lady 

I just beat the main quest and most of the side quests. I would say that so far I have put in about 30 hours. I'm going to get all the DLC packs now so that should bring me up to maybe 50-60 hours?

" Around 250+ hours across 3 characters. And I'm nowhere near done with it. "

400+

A little over 48 hours as of this morning.  Finished main quest last week at about 45 hours and now i'm on to the Broken Steel stuff.  I still have a TON of locations to visit.

50 hours or so.

250+ I think, and I dont have any expansions for it.
 
2 level 20 characters before the trophy patch, 1 more level 20 after the trophy patch.
 
And then a bunch of smaller charcters with 20-30h logged into them.

About 30 with my first character and about 20 with my (current) second character. 
 
I'm about to get to level 20 so I can't do too much more until Broken Steel comes out :(

74 hours every dlc complete :-D

almost 10 hours. I haven't played much.

30 hours on my first play-through and I'm not going to play it again until the DLC comes to PS3 :P

Here is an updated view: I just broke 80 hours on my first playthrough :D YEAH ME!!

Around 50 hours with two characters

85 with one character.

About 42.

I rented it and in 3 days put 23 hours in the game, going to get the game of the year edition.

i plowed through the main quest first time through. havent touched it since.  but ima get the GOTY edition this fall so i will have a lot of shit to do in it

Right at 130 hours for now, havent gotten the new dlc yet.  After I played fallout 3 I didnt think I would find another game to grab me for that long for quite awhile, then Demon's Souls came along.  I just clocked in 170 hours in Demon's Souls for the platinum...... and then I remembered how soon Borderlands will be coming out, man these games are killing me.

I have put in around 60 hours and bar a few quests I feel i am done with this game.

I hav 156hrs on 1 character.

About 80 or so hours with my 1st save, but im stuck on Mothership Zeta. Those damn teleports glitch out way to much.

Bought the game the day it came out, have all the DLC packs, JUST got up to Broken Steel (have Zeta to start and Point Lookout to finish) and a boatload of sidequests to do too.. and I'm at 96 hours.
 
I like to take my Bethesda games nice and slow, and I'm loving every bit of it. :)

110 hours on PC and I have 2 more DLC packs to go through.  Thank God they quit putting out content. 

" I hav 156hrs on 1 character. "

I'm sitting at about 80 hours total.

52 hours, spent alot of time exploring, doing side quests and messing around.

I have put in around 105 hrs. I think I'll get the PS3 version now and become a trophy whore! I'm looking for an excuse to play another 100+ hrs!

I'm sitting at roughly 90 hours between two characters.  With my "Good" character I have about 60 of those hours, playing through Broken Steel and Point Lookout (both of which were awesome, by the way).

I have put in about 58 hours on my very 1st char.  Still playing though.  I finished the Pitt and have now started Broken steal and have just got to Point Lookout.

Less than 10 hours i got bored playing it so i sold it to a friend of mine

"Less than 10 hours i got bored playing it so i sold it to a friend of mine "

80 hours with Broken Steel the only completed DLC, dipping in and out of the PItt atm.Havent played for a while

All together (from both my playthroughs) probably over 100 hours...
