How long does it take to beat the game?

I had about 55 hours on my first playthrough, with about half of the optional content done. I pretty much skipped most of Elaaden and H047, but I was pretty thorough for Eos to Kadara.

I'd estimate the critical main-story-only path to be 25-30 hours, with 40-60 hours of additional content, going by how I usually play.

However of course the difficulty and your personal playstyle is going to have a huge impact. If you play on Casual and with a focused style you'll tear through the combat encounters like a freight train. On the other hand a max-difficulty run with certain builds would take much longer.

Some people will want every detail of every random NPC's story, others will spam past spoken content while skimming the subtitles. 

I'm one of those David is talking about regarding every detail.  100% on all planets for Viability, side quests, hidden caches, etc.  All ship models.  Level 70.  All crew loyalty missions.  Everything and everyone saved.  So forth.  I have 3 tasks that are bugged, but outside of that, I don't think there is anything else.  Took a little over 100 hours.

My playthrough took just under 100 hours with pretty much all side quests that I could find done, though I skipped a lot of the additional tasks.

87% complete on the first game in around 50 hours. Level 45.

57% complete on the second in around 20 hours. I think level 60 (New Game +)

Now I have three characters over level 100. Lot'sa hours now. lol

I have just finished the game at level 60 and I have done pretty everything expect 7 secondary mission.

Helios discovered at 95%.

How can you have finished the game at level 74 with a single run?
