About 8 hrs and I felt like I rushed it.

What, you reach the Strip in the game?  *SPOILERS*

" 48 hours played right now.  Haven't touched the strip, even though I have way more than 2,000 caps, can get a counterfeit passport or can get a real passport from The King. "

" @TheSeductiveMoose:  I just type "showracemenu" in the console if I decide I need to change my face or hair. I inadvertently started with a little bit of chin hair, went to a mustache and goatee, then to a beard and then finally to the shaggy beard. All by accident, really. "

I've got 19 hours logged so far and I still have no intention of entering Vegas.

" @TheSeductiveMoose:  Changing cells? I've only used it maybe...three times now to change my face. "

I didn't do that many side quests early on, so it only took me around 6 hours to get there.

About 6 hours, but I didn't continue with the main quest until 25 hours in.

I'm not sure how many hours it took, but I was somewhere between level 20-25. Yeah, I did a lot of side quests before ever stepping foot in the Strip.

Around 30 or 40 hours I think.

About 25 hours in..

Myself entered the strip at level 29. Guess played time was about 35 hours at the time.
 
I took very early in the game the explorer perk so I was able to see most of the locations on the map right away. So far I have explored over 125+ locations. I am pretty
amazed about the amount of guests that the developers have been able to include into the game. 

 I am also glad of the fact that  enemies in the game are a challenge even at level 30. In earlier fallout games the minigun in particular was a weapon of mass destruction. 
 
Been playing the game in normal hardcore mode. Respects to the people who are playing the game on hard. I dont even want to imagine how tough the Deathclaws are in that difficulty level. Though I have managed to amass quite a few c-4 explosives. Problem is finding detonators for those though.

7 hours.

61 hours still not there......just too much to do elsewhere

I was about 38 hours in before I went into The Strip. Was sooo much to do on the outside of Vegas so decided to leave the main plot for as long as I felt I could. 

12 hours in and I aint there yet.

Still on my first playthrough. Took my sweet-ass time to do anything in the main questline, so didn't see the strip until at least 60 hours in.

First play through was probably at least 20 hours,  did ever quest i found before i went into the strip.

Didn't see the strip till past 30 hours. 

" these plus 30hour answers are blowing my freakin mind. You guys just wander the Mojave for ages? "

I was at about 30 hours, maybe under, when I finally got to the Crimson Caravan Company the other day.  I swear I spent like 2 hours just going through all the various places around Camp Mcwhatsitcalled, and another good hour or so just making a big circle around New Vegas and discovering all the gates and places just outside the strip.  I also started (and have remained) Hardcore mode.
 
I'm definitely the type to put off the main questline as long as possible and do all side quests first as I come across them.  This could be why I have trouble finishing games.  Although I think some of that 30 hours was walking away from the game for a bit (like to do laundry or something) and forgetting to pause it.

About 24 hours for me.  I like to take it slow, explore.  The great thing about Fallout games is that this approach is very rewarding.

I'm at about 35 hours, and still haven't ventured into the Strip.

Finally went to the strip at around 60+ hours.

I'm at 33 hours and have avoided the strip so far.

Took me 22 hours.
