Well…

I was reasonably engaged by the story of Mass Effect, and I was particularly pleased with the background lore for the various races and technologies.

Certainly, I was FAR more interested and enthused by those aspects of that game, than the utter messy boredom that was Alpha Protocol story/characters.

Mass Effect 2, though, much less interesting than the first one - but still significantly more interesting than AP as a cinematic experience.

As a pure gameplay experience, Alpha Protocol was better than either of the others.
