Unmarked ME Trilogy ending spoilers incoming.
I just finished my first ME3 (and full trilogy) playthrough a few minutes ago. Now, I was one of the biggest nerd-ragers about the original ending (I'm sure if you look through my post history, you'll find it), and it put such a bad taste in my mouth that I largely ignored Mass Effect media and DLC and such until maybe a year or two ago, the main thing being that my girlfriend of a year plus is a huge ME fan and got me back on the positive thinking train about the series.
Anyways.
I just finished the ending, and it was so much better. Now, I played the Extended Cut back when it came out, and while it was better, it didn't fix the problems I had with the ending whatsoever. Now, given time, the Leviathan DLC, and maybe just an entirely different mindset, I actually enjoyed the ending for what it was.
Having full explanation of what is actually happening from the Catalyst, actually having some backstory of his origins from the Leviathan DLC, having proper closure with the crew in Citadel DLC...it just all tied together so much better. I ended up being seriously torn between Control and Synthesis, while in the original I picked Destroy (now, why would I kill EDI and the Geth after what they've done?), I ended up picking Synthesis, because while I'm not 100% convinced synthesis was inevitable, it was the best solution. Having that much control over the reapers with no certainty about your personal future (and basically being a god) is a little...unsettling and a bit too much power to wield as one human. Let society choose their path, not Shepard.
Anyways, just wanted to get this down, because I went into this trilogy playthrough dreading going through the ending again, after it legitimately angered and saddened me the first time around.
Now I'm even more excited for Andromeda. Day one!
