Now that I've played DA:I, I would probably say that I liked DA:O better. And I fucking hated DA:O's Fade nonsense -- that shit could've been edited right the fuck out, seriously.
DA:2 is an entirely different experience. Not that it wasn't pleasing, but it's very clear that BioWare (under pressure or not) wanted to move away from DA:O's tactical play.
Why did I like DA:O more? Because I gave a shit about my elf from the slums. I gave a shit about my slaughtered family. I had a reason to hate Arl Howe.
Why did I like DA:2 more? Because I gave a shit when Bethany died. I gave a shit when Merrill (bless her heart) lost everything that mattered.
I really don't give two shits about my Inquisitor. She has no backstory. And who am I supposed to feel for among the Inquisitor's compatriots?
Right. The writing in DA:I is the weakest, in my opinion. And that shreds the shit out of my enjoyment. Everything else is cool as fuck: the open-ended feel, the multitude of "adventures," the strategic task setting for my advisors, and so on.
