How long will it take for you to complete MEA?

I like to really listen to the dialogue and will often reload and repeat conversations immediately in different ways just to get a comparison... then I usually go back to my original choices before carrying on forward.  So, some of it will depend on whether or not ME:A allows for manual saving like that on the consoles.  If it does, then my 1st playthrough will easily go over the estimated 100 hours regardless of whether or not I decide to do all the sidequests.  If it doesn't and if I'm not really feeling a good connection to all the side-quests, then my playthrough will be a lot quicker... probably around the 60-hour mark.

My first playthrough sometimes gets aborted.
My 'perfect' playthrough might be #2, could even be #3...

My average for the Trilogy is 21 hours so probably 20-30hours. Exploring really isn't my thing, I want to shoot things.

Forgot to say for myself.

I expect I'll get sucked in little over 100 hours in ME:A, just like in DAI, for my first run.

In previous ME games, it took me close to 60 hours to finish ME1, while 70+ hours for both ME2 and ME3. With everything shown so far, ME:A should be able to get me to play up to 100+ hours. And I'll still fail 100% completion rate, I just know it.

100+ easy because I like to do everything and take my time doing it!

I have no idea how long it will take to complete the game especially for my first playthrough. I will say at least 50 hours.

If I like the game, I will do a quick playthrough to see how long it takes to finish the game

I've completed DAI in 10 hours on the ps3. I haven't tried to see how much faster I can complete the game on the ps4. Maybe one day I will.

Not saying it's bad but I don't understand how people can go 100+hours on a single playthrough! I would go insane! I want to finish the story asap!

An hour in tracel time? Do you walk everywhere? There is thes little thing called the Mako, seriously if you spend more than 5 minutes traveling anywhere you're doing it wrong, just skip combat and get wherever you're going

Likewise! I'll search a planet three times if I have to just to make sure I found everything!!!

I can't find the tweet at the moment, but it was either from Mike Gamble or Ian Frazier. One of them mentioned that the Critical Path would take around 15-20 hours to complete while the full game would be around 120. It was a few weeks ago if I'm not mistaken. Perhaps somebody can track it down.

A chip off the old block!

Agreed. I like being thorough and making sure I've seen everything before progressing.

I like to fully immerse myself and know that I saw everything. Otherwise, it bugs the heck out of me if I skipped anything. Then again, I'm the kind of person who spent over 500+ hours playing modded Skyrim and 200+ hours in The Witcher 3. I just enjoy doing as much as I possibly can to gain the full experience of the game.

wow 100+ hrs??? I didn't expect that to be winning.

I am hoping it takes at least 60 hours. I know if you shoot through the main quest it only takes 15 to 20 hours so here is hoping the optional content is flushed out really well.
