I boggle at the naivety in this thread.
Regardless of how you feel about the game, this much is certain: they rushed DA2 badly. You can see signs of it everywhere, from the recycled environments to the abridged fetch quests. And if you don't believe your own eyes, trust the soundtrack's composer; he basically outted them for rushing to market. 14 months in development when the original game took five years? C'mon. You don't save that much time reusing a mediocre engine and a few assets.
So why did they push for such an insane timetable? Why compromise the quality of your product so blatantly? Was it for us? Did we need DA2 right this goddamn second? Of course not. They did it for money. That's it. They wanted to shorten the dev time and pocket the savings. Sure, the game suffered, and yeah, some folks would hate. But brand loyalty and intense marketing would generate enough sales to bridge the gap, right?
Now here they are giving away free copies of ME2 if you buy DA2, and people are gullible enough to defend this as benevolent behavior? Isn't this the company that just knowingly rushed a game to market, with clear negative side effects, in order to make more money off the lot of us? Why in the world would they do something so contrary to the character they just demonstrated not two months ago?
If you benefit from this promotion, great. More fun to you. If you loved DA2, fine. You were somehow well-served by their short shrifting. Me? I've got a crazy idea. Instead of so generously taking a bath on a game giveaway no one asked for, how about you go ahead and save that money so you have enough to properly finish your next sequel.
TLDR version: it's a promotion aimed at counteracting the immense (and deserved) dropoff in DA2 sales.
