has multiple games, and each game includes a variety of different dialogue options that change the lines that Commander Shepard, their crew, and NPCs in the universe say.
While many lines of dialogue fit the situation and don't stick out enough to think about after the moment passes, others end up quoted by players even years after they've finished the game.
With so much dialogue included in one series, it's natural that some lines have become iconic within the community. Each game in the trilogy has a different villain that Shepard faces, but the primary enemies are the Reapers.
This creates a serious tone, which leads to some rather heartbreaking lines that leave a somber feeling for the crew. However, there are also lines that are unexpected and funny, especially with the heavy plot lurking in the background, which manages to make them iconic and quotable long after the credits roll. The Council is an annoyance at the best of times during the entire trilogy.
Shepard does their best to convince the Council that Saren and the Reapers are threats to the galaxy, even if Saren seems to still be playing the role of a respected Spectre and there's no evidence that Reapers exist.
