'I dislike or hate the game' (General feedback)

Compare it to ME1, not what ME3 was as a biproduct of 1, 2 and itself, please.

To hammer this point down, try to remember back to your very first playthrough of ME1 and remember how attatched you felt or how much you care about the plot before ME2 and ME3 substantiated the themes and backstories built up by ME1.

That said, I think it's weaker than ME1 because it skimps way too much on context but I have a feeling this is due to poor planning and cut story segments (happens in very game; then they have to reassemble a plot from the remaining setpieces) and not because they're just dumb writers. It's also an issue of "too many cooks in the kitchen" though.

That said both MEA and ME1 had around 5 core writers to shape up the backbone and lore. The remaining 5 writers came on later and similarly Patrick Weekes did not join ME1 until the very end when all they needed was extra side missions.
