How many playthroughs have you completed?

10 for the trilogy. I think one of them started in ME2.

3 ME:A.

lost count, probably over a dozen of ME2-3 and maybe half that of the first game (it wasn't available on PS3 until ~2012, I think?)

ME1: 10-15, used to do a playthrough once a year to honor such a great game, might start another for N7 Day this year.
ME2: 10-15 as well, probably the most 'accessible' of the trilogy, my playthroughs in this are normally pretty speedy.
ME3: less than 10, the impenetrable shadow of the ending leaves a stigma hanging over the whole thing, and to be honest I really only boot up to play the Citadel DLC. Plus, I've sunk in over 600 hours into the Multiplayer, and that always draws me in.
Andromeda: 1. Finished the main story at launch and called it quits. Connection issues with the Multiplayer sealed the deal.

Six full trilogy playthroughs and halfway through a seventh. Two soldier and one each for adept, engineer, sentinel and infiltrator. Currently playing as a vanguard for the first time (and not enjoying it tbh). I only discovered ME two years ago so all games were available to play off the bat.
40hrs+ of ME:A before I couldn't take any more.

Yeah Vanguard is my least favourite class in the trilogy. Mostly because I think I prefer more ranged combat I'm not good close in and I feel too exposed. I do enjoy the biotic charge though and zipping around the battlefield using it. But I do enjoy all 6 classes though.

ME1: 3
ME2: 8
ME2: 2
MEA: -

First infiltrator play-through ongoing for ME2. Never played vanguard either.

I don't have an exact count, so these are just guesses:

ME1 - 15
ME2 - 10
ME3 - 8

At some point, I just knew all the dialogue so well, there wasn't much point in re-playing it. However, I haven't touched the trilogy since 2017 so I am hoping it will feel somewhat fresh when I give it another go with the remaster.

More than I can keep track of. This trilogy just does not get old for me. Not that I won't play other games but I always make time for new trilogy runs.

10 trilogy runs or something
ME:A 6 times, I think.

I think ME:A is the only game that captured the sense of wonder that the original Mass Effect gave me. Still wanna know more about the Vaults and the Jardaan.

Well unfortunatel yon eclass ahas t obe a least favouriet and Vanguard is it. I generally prefer to keep my enemies a trange and Vanguards aqer at thei rbest close i ns oit doesn' treally work for me as well as other classes do. I d oenjo yplayin git as I do stillenjoy the Biotic charge and all that but I prefer to keep my enemies at a distance. Vanguards just don't normally fit my playstyl ewhen it comes to playing the trilogy
