Legionwrex: Mass Effect doesn't offer 6 PLAYABLE origins like DA:O, and many reviewers still consider their handling of the prologue to be unparalled in the history of RPGs.

It was also one of the most morally ambigous RPGs, as they have ditched any sort of the morality system and let players choose for themselves what is morally right and what isn't (for instance, I find sparing the Anvil of the Void and creating more golems to be far more moral than abandoning it, etc.), which is vastly superior to the Paragon/Renegade system, especially after they simplified it in ME2 (red facial scars? A star turning from red to blue based on your choice? Why?!). Needless to say, this also meant that the dialogue was considerably more complex than in ME.
