Funny thing to add to this:
I played through the opening section of Inquisition and, as I said, realized I was no longer as familiar with the world as I was when I last played a Dragon Age game. So I played the Dragon Age 2 DLC, and realized I quite liked that game - despite it's flaws. And really, the DLC's show how good the game could have been if it had been given more time.
So I could not resist the call of Dragon Age any longer, it has sunk it's claws into me again.
And so I've started playing it from the very start now, and intend to go all the way through in chronological order:
Leliana's Song > Origins > Awakening > The Golems of Amgarrak > Witch Hunt and then Dragon Age 2 + DLC. Then, I'll play Inquisition again.
I'll be going mage all the way through, because mage is awesome. But damn, don't they feel lame in terms of animations in Origins?
Standing there, shooting their stick with a bunch of glowing effects on the whole team... But you can go Arcane Warrior! Which makes you an indestructible deathmonster that pretty much breaks the game
Honestly though I think I like the focus on teamwork in later games more, as Origins feels like a really good game of chess, or well, a strategy game, compared to a frantic battles that forces you to change tactics on the fly in DA2. The pacing might even be a decent mix of the two in DAI, but I've not played enough to judge that yet. Anyhow I'm just a lot more engaged and active in fighting in the later games.
I also prefer the animation, armors and general aesthetic changes to make things look more unique in later games. Except for the Darkspawn in DA2, they look scary in Origins and sick and weak in DA2

Poor Hurlock, so sad. Didn't even get to keep his armor, or his teeth
