...do you even remember what Bring Down the Sky is about? Batarian terrorists were going to drop an asteroid onto a planet with millions of humans to wipe them out, along with every living thing on the planet. That's not small scale. It's easily on par with "find out who's been abducting small human colonies."
Yeah and I'm pretty sure they didn't save the galaxy and a small colony even with millions of lives when compared to all the life in the galaxy is small scale. Its not like you are recuing kittens from trees in Halo Reach. Planets are in ruins, huge invasions etc. And yeah your team plays a big part in those events. So by smaller scale saving one colony is a similar goal.
I have no idea why you went off on this tangent.
It was a illustration showing that people might not like things, might have a poor reception for things, might get sales down for different issues than you assume. Was DA2 smaller scale. Yes, but you don't have any evidence that is the reason for poor sales or its dislike. Correlation vs causation. I think poor gameplay killed it, not its plot.
I like them too, but sales figures don't lie. When you're playing those games you always know that the story and characters you're playing don't matter. When you go from "savior of the galaxy and Head Bad Ass In Charge, Master Chief" to a normal soldier or a nobody Spartan that died without any recognition you tend to muster up less excitement.
And was that due to it being smaller scale o to it being a side story, kind of like how a prequel for ME would likely do worse even if it was just as large scale as the original trilogy,
