Mine is about 15 hours, and only 14% complete.  It's insane  I'm never going to get everything done lol.  I love just screwing around too much.

23 hours @ 39.98% complete... been workin to wrap this game up nicely at 40% but it's amazing how much .01% equates to the amount of destruction you need to dish out. Great game btw!

Just passed the forty hour mark. Real close to 40% complete. I've finished all the quest/faction missions, but have basically left the challenges untouched.

I'm just past 15 hours and I have 22 % complete. How did I manage to get over 50% of your completion in the same amount of time, Arch? Weird. I'm not doing anything special, just friggin around and doing missions.

I spend an insane amount of time trying to fly my plane as close as I can to another and hijack it with the grapple hook. Then when I'm in the new plane, I watch at the other one spirals down and blows up! 
 
That, or drive the airplane into a building and jump out right before it crashes so I can watch from my chute! 
 
Probably spent around 2 hours doing just those things, haha.

My final time was close to 50 hours, with about 65% completion. I was really pushing for that 75 marker, but once I had finished all the missions and challenges I wasn't really looking forward to clearing out towns and whatnot for the next 10 hours.

I'm about 40 hours in and i have 53% complete. I've gotten 100% on around 140 different locations, completed all story missions and faction missions, and completed a little less than 20 challenges. I don't plan on quitting until i get to the 75% point. One thing i'm not liking at this point is that there's no real since of completion, after destroying a military base or airport it would be nice to see some of your faction buddies take it over (much like the stronghold) or maybe a slight decrease in military presence in surrounding areas making taking more areas progressively easier until you have reached your goal of zero military presence. 

I'm 20 hours in and right on 20%. Its been tons and tons of fun. Haven't been doing too much goofing off. I pretty much just use my grapple to travel between missions and any towns I come across on the way I blow up everything in them. Except for the Strongholds. Every time I get a new one I take about half an hour to an hour to 100% it.

Somewhere around 32 hours and 42% complete.  Once you enter Mercenary Mode its amazing how slowly the percentage ticks up.  I've been doing less screwing around and more clearing of villages/bases for the last 10 hours and I'm still forever away from even the intermediate completion achievement, though the collectible achievements are within striking distance.  I'd estimate that it would take me another 25 hours at least to get up to 75% complete though, which means that's not going to happen.

Same. I think a good ten hours of my playtime has consisted of me just fucking around and causing insane shit to happen. "

Mine is 64 hours 87%, still fun but no real completion feeling.

 
37 hours,59 percent completion.

I have about 30 hours in the demo

23 Hours. 38%

Just over 16 hours and 25% complete for me.

30 hours 17% complete.

I beat the game at about the 25 hour mark, with a 33% complete.
 
Taking a short break from it, but I've still got a lot of hours left to put into this one.

I'm currently at about 50 hours with 67% complete. Just trying to get to the 75% mark for the trophy then I'll mop up any other remaining ones I have left.

Currently 40.9 hours played, 41% complete.  I've been avoiding many of the missions and just running around clearing towns though.

60 hours @ 84.66%
Thats with faction missions cleared and towns cleared... im sure if i did the challenges and drove all the cars i'd get to 97% or so but i dont know if can play this game ever again. Clearing out the Panau city districts made me hate this game so much >.<

53 hours @ 61%
I agree about the Panau city districts, after hours of flying/chuting/running/driving around just one of the zones and only getting to 91%, I've decided that those can just stay incomplete.  Have done about 20 faction missions but only 3 of the story missions so far, have been clearing islands / challenges / faction items.

34 hours. 47.88% I will never get close to the 75% achievement.

22 hours, 35% complete.  I've all ready completed all the missions, so I'm pretty much done playing it.  Might hop back in every once in a while for some grapple hook goodness.

Can't remember my percentage toward completion, but my play-time was 25 hours.

61 hours @ 72%
Finished the main campaign, working towards two more achievements - trusted ally (32/49 faction missions) and up to the challenge 2 (46/50 challenges completed).  Luckily there are well more than 50 challenges in Panau so I can avoid some stupid ones like Bridge of Death which was just madness.  Driving ones are a cakewalk, boat ones are even easier unless they have you jumping strips of land (when you often have to bail and pay for the BM boat), flying ones are generally easy since I'm used to flying low and under bridges, but the base jumping ones are just frustrating.  Will finish off these achievements and then rock through the game on the hardest difficulty for the two achievements I'll have left.
 
Still loving it.

about 37 hours and around 41% ( completed all the agency and faction stuff, going to start with racing and completing villages :D ) first game in a long time that keeps me playing this long and keeps being fun to play :D
 
grtz Allen :p

" 34 hours. 47.88% I will never get close to the 75% achievement. "

Playtime 52 hours and 75% completion. 

The game would say about 15 hours, but my steam says 30 xD I'm only about 15 percent through the story.

102 hours, 61% but much of that is my son pissing about...

I rented it out because Im a fool, got about 6 hours in and completed 9%.

I'm obviously lagging far behind. 9 Hours and 7% Complete.

I managed 79% completion in 60 hours. Completed every faction mission, cleared out a ton of villages and stuff. Tedious but worthwhile.
