Lets all join hands here... what was your "moment" with ME. OT or MEA.

As a PS3 player I started with ME2 on the suggestion of a buddy who was impressed by it's shooting mechanics and gameplay. We were huge Socom fans mourning the loss of our once great series. So I tried the demo. It was pretty fun and enjoyable and he tells me about the story: Giant spaceships that secretly exist as killer robots that can control and influence those riding within. It reminded me of an awesome concept from an album by The Faceless. Planetary Duality; living breathing planets that exist to destroy. Still, despite all this backstory and awe it hadn't hit me yet. Until Mnemsoyne.

That reaper ship scared the fuck out of me in a good way. When you first step aboard and see its wires and ominous setting. The music, the husks, learning of the Protheans. It all hit me. I absolutely LOVED everything about ME2 and still do. The setting and presentation was the best. I loved the color palettes and the "dark side of the galaxy" backdrop.I couldn't get enough of it. It still gets me today. It's one thing Andromeda needs; darkness and mystique. A more mature tone with more present music and greater effort in the settings. I love this series.

Ilos and Vigil.
That was a small piece of perfection.

ME1 was the game that made me a ME fan. I did played ME2 before and wasn't super convinced then I played the first game and knew that I would love this franchise. The specific moment I realized that was on Ilos with Vigil reveleations and the sad history of the Protheans.

The end of ME3. Not because I hated it, but because I actually really liked it and it drew me back into replaying the trilogy. I liked playing the series for the first time a lot, but I never was a fan of Sci-Fi (or shooters, for that matter), and thought it would be the only time I'd play it. By the end of ME3 I was hooked so much that I keep replaying ever since I finished ME3 2,5 years ago, and I won't stop for a long time. MET has become my favourite videogame experience and I cherish a lot of moments in it. Way too many probably

I second that.

When you first arrive to the Citadel after Eden Prime. That whole cutscene still feels amazing after an insane amount of PTs.

Completely agree. The design of the Citadel along with the music is just a perfect moment.

I was hooked from the moment the main theme swelled over text describing the mass effect. The moment that will remain with me til my dying day is the paragon interrupt during Tali's loyalty mission. Wrapping her in a gentle hug as she cries.

That underwater intonation in the music couldn't have fit anything better than it did Leviathan, though. My only real problem with the MEA OST is it's a little muted in the game. I've listened to the whole MEA score outside of the game and it's really good. Maybe not as mind blowing as some of music in the OT but it's still really good.

That was a big deal for me as well.  Music is such an integral part of ME's universe... it was really a let down that during the most pivotal moments of ME:A the music was basically background noise.

Speaking of music and awesome OT moments... this ring a bell for anyone?
