Hi, fire up L.A noire from your console and only post your actual game time and game completion percentage. It has to be from the game down to the very second, no I think I played it for 20 hours because that's not helpful. Also post it only once, if you have a significant difference in game time and completition, re-edit your post then to reflect that. Also feel free to comment on the replay value if you like, I was suprised I spent this much time at the game.
 
-----------------------------------------
 Why are you making this thread hitman? 
 
-I made it because I always thought maybe L.A noire will have no value once you finished everything. I even bought a second rockstar game to supplement this game. Now that I realised there seems to be a ton of replay value, I want to see a general concensus about it and to see if others played the game as much as I did. I am sort of trying to get a general concensus to see if others share the same replay value I had.
 
Okay cool, so how should I post in this thread? 
 
Like this, My game time is: 33h 27m 21s (H = hour, m = minute, s = second) and my game completion is: 83.4%. 
 
What if I am not near my console now and I sort of know roughly what my game time is?  
 
post it when your near a console. Take your time to get the numbers correct, it's not a competition. The data is important to me to see how much everyone played it.
 
Can I comment on the replay value besides posting the specific numbers? 
 
by all means sir, by all means

My game time is: 19h 23m 59s and my game completion is: 70.5%.

36h 1m 41s - 100%

20h 40m 29s
68.5% completion
 
I didn't find a ton of replay value, collecting cars and film reels is not really fun.  The side missions weren't too fun after awhile either, driving across town just to shoot two dudes just made me lose interest.

21hrs 32 mins and 71.2%

48H 57M 14S - 100% - Main game only, black and white. I'll play a fresh game, in color, when all four DLC cases are out.

@Marz: Did you replay the game twice? I did because I wanted to get 5 stars for every case mission.

 
15h 31m 2s- 82.1%

30 hours, 0 minutes, 45 seconds, 95.9% completion. In my opinion, the replay value of the game is close to zero. I replayed some cases, but found them tedious a second time through. The collection hunts were similarly tedious. Hunting down cars was about as fun as collecting stamps, which is when I stopped. Of course, your mileage my vary.
