Hey, I also enjoy reading Agatha Christie crime novels and seeing them on the telly, too :p
And they all seem to be the revolving around the same plot i.e. a varition of the butler did it
Sometimes the butler is petty thief, sometimes the butler is the dashing foreigner, other times the butler is well, some one else. But all mrs. Christie's villains seems to come mostly from the underclass, people that aren't happy with their station and lot in live and as such will do everything, even murder ;( , to get ahead in life...
The same can be said for Bioware's games. We know we get romances, a major stunning plot twist, possibly a traitor of some sorts and a storyline about someone saving the Forgot--- eh, I mean the universe. And you get to play the daunting hero or heroine...
And yes, the ancient evil could be global warming, but then again, it could also be something much much worse...
I'll like to reiterate that I think it is a :wall: business move for Bioware marketing Mass Effect as a shooter, simply because the shooter crowd won't get why they just can't blow up everything...
