It's not about the conclusuion but about the whole journey. This game perfectly captures the feeling that the whole galaxy prepares for the war and makes you feel like you participate in one too, I really cared about saving every race. Very hard decisions to make but it finally finishes some of the most important side-plots, giving some of the characters the ending they deserved.

Kinda sad that most of the ME2 party members are left behind and are not present during majority od the game, but playing citadel dlc somehow makes up for that. I also adore how the characters move around Normady and interact with each other, this makes the crew feel a lot more alive than when they were just sitting in their places doing their jobs like in ME1&2.

I know that the ending is controversial, but I don't really mind, either way the Shepard's story feels complete, and it's written in a very emotional way.

Flaws for me is not being able to hide the weapon during missions, and the body proportions&eye movement feels a bit weird comparing to ME2. My Shepard felt like a different person the first time I imported her, but eyes can get used to it.
