Man of Honour
Idk, im like an hour into 3 and im already seeing my choices from 1 appearing e.g. liara looks at me with this death stare every time i talk to another woman. Ashley is alive rather than kaiden. when i went to speak with liara the shadow broker vi is there (before people say that happens anyway, its nice to remember it from 2) and then you continue your relationship with her again. i'm looking forward to finding wrex and all the crew members from too, which i saved every last one of them.
For those that say that the ending, the last 30 minutes were a let down. Its another choice just like the rest of the game. is me3 not meant to be the ending to the Shepard story, i.e. the entire game not the last 30 mins sure she talks about the reapers coming back in one, again in 2 and in 3 oh look who the **** showed up
THE
REAPERS
The ending is defeating the reapers and that is what 3 is you finishing the 3 part long series and depending on what you did in 1 and 2 certain things (mainly socially and to do with who is alive and who isnt) will be different, not the entire game.
Sure, you might get one or two lines of different dialogue here and there, or a cameo from someone, but the actual story and plot does not diverge from the same course, no matter what you do.
My example earlier was having a mission about the Rachni queen being captured and you have a mission where you can save her again or kill her. If you killed her in the first game, then ME3 just magicks another Rachni queen out of nowhere, just to keep the story the same.
Another example is the Geth missions where if Tali is...not accompanying you, you get a slot in red shirt character (Daro'Xen) who does the exact same things as Tali would at the same time. Ergo, the story and plot is no different.)
These whole things make ME3 feel plain and not 'personalised by choices'.
