I remember way back when DA:O was being marketed as a throwback to the old IE games, like Baldur's Gate, Planescape Torment and Icewind Dale, to name a few and touted as the spiritual successor to DA:O. I also remember when the first talks about a more action oriented DA2 started and how the community back then demanded answers as to what was going on with the legacy of that spiritual successor. Most of the people that craved something like that have, admittedly, walked away from DA and Bioware in general, to some extent, since then. Apparently, EA and Bioware does not seem to regard us, my demographic, people that have been playing cRPGs for, perhaps, well over 20 years, as important.
So a line was drawn to draw in the crowd that is more attuned to the instant gratification of the more action oriented combat scheme. That is to say that I do not consider action/arcade style games a bad thing. I am an avid fan of the Devil May Cry franchise as well as games like Dynasty Warriors, but I do feel that Dragon Age traded some of its identity to become something that it inherently wasn't and, to a degree, imho, didn't need to be.
There's also the approach of more adult themes, like gore and sex, that weren't touched to such an extent in Baldur's Gate. While Baldur's gate did, indeed, have romances, the stances of the characters towards them weren't as provocative as they are in the DA games and were, again, imho, more tactful and much more sentimental, not so necessarily "in your face". I mostly dislike about them the fact that you can't actually be a friend to a potentially romanceable character, but are automatically locked into a romance with them, if you are nice to them. And if you want to get to know them better, you have to romance them.
There does, however, seem to be a comeback of the old IE games with titles such as Blackguards, Divinity: Original Sin, Torment: Tides of Numenera, Wasteland 2, Expeditions: Conquistador, Pillars of Eternity and a few more that I am sure I am forgetting. It wouldn't be bad if Bioware could tap into the potential of those demographics a little more, would it?
