Brooding, more serious. Can we expect that from Mass Effect? According to BioWare co-founder Greg Zeschuk:

"If you recall, Empire Strikes Back was the darker chapter and that is how we designed the ME2 story and experience: to try and make the player reflect on the challenges of the character." Continuing, he tells IGN, "If you put ME2 next to the original it is definitely a darker, harder game." Zeschuk is reiterating what http://kotaku.com/5353339/mass-effect-2-is-more-than-what-meets-our-eyes">he told Kotaku back in September.

The second Empire Strikes Back took the Star Wars characters and put them in the worst situation imaginable — well, not as bad as putting them in the newer Star Wars movies, but still pretty bad.

Mass Effect 2 picks up "soon after" the first game as Commander Shepherd is crewing up "a dozen of the galaxy's most dangerous operatives" just as a new menace threatens to wipe out the humans.

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!
