On further review, I guess the shortness of missions is counteracted by the number of them required to finish the game. I did very few sidequests (saving them for post-game), and it still took me something like 34 or 35 hours to beat ME2. Maybe it was the lame summary screens after each mission. Honestly, I think those were unnecessary.
As for the save the base stuff, I’ll defend it thusly – understanding what’s in the base gives us more understanding than letting go of all of the information. Whether or not that’s how it’s going to be used in ME3 (and based on The Illusive Man’s interest in it, I doubt it will be), that was my rationale. I don’t think it’s evolving on the path the Reapers set out as implied by Legion, but learning about them so we can stop them.
Also, you guys didn’t tell me who died on your first playthrough of the game. So do that, huh?
