Thanks, OP. Now that you mention it, things have indeed been rather nice around here lately. Lots of interesting discussions; hate and trolling, while unavoidably not completely absent, have been relatively rare. A very welcome change after the post-ME3 mood.
Passions always run high right after a game is released, but I think DAI has had a reception as balanced as you can expect from a game that had a noticeably smaller plot than originally planned, and certainly a much better reception than Bioware's previous two games - DA2 and ME3. That has contributed to a fairly moderate mode I think - well, as moderate as your typical fans' mood ever gets.
I also think that what is "typical" for Bioware's forums - in whichever form - has been distorted by the fact that their two games before DAI have been rather controversial at the very least. Thing have simmered down to normal since then - a fairly moderate mood interspersed with specific high-tension or high-passion topics and the occasional political trolling attempt.
