Glad to see, that Im not the only one who thinks that Origins is still the best. Up to date, its still my favorite game of all time, because its filled with tons of atmosphere and story on which you can actually take a strong influence. My favorite was the Orzammar quest line. It just made you feel as if you were actually in a kingdom under the earth, heated and enlightened by glowing lava, with its own society, history and culture. I was hoping we would get to go back to that place in future games to discover more of the dwarves history while influencing their politics, but no such luck so far.
And the music of this game was incredible. Just listen to this: https://youtu.be/CdKwLkEGjhg
However, I hated Dragon Age II. In my opinion the story of Dragon Age II was just the worst of all Dragon Age games. It lacks depth and Hawke is a boring character, along with most of his companions except for Varric and maybe Anders. Characters in this game generally sucked. Not just the protagonists, but the antagonists and NPCs as well. And I also didn't like the engine they used to create that game. The maps were boring and dull and failed to give me any feeling of the same atmosphere that I loved so much in Origins. Shame on Dragon Age II. My first thought when I played it was: "For heavens sake EA! What have you done you monsters?! You murdered Dragon Age!" Thats all I have to say about Dragon Age II. It should be treated the same way as the citizens of Reborn treated the waste in Bysbixion: Build up a wall and lock it away forever, so no one may ever stumble again upon this mess.
Dragon Age Inquisition came pretty close to Origins in terms of interesting characters, maps, and story. However, it still lacks much of the atmosphere that Dragon Age Origins had, as it feels more like the foundation of something bigger instead of being an epos of its own. There are just a bit too many cliffhangers and unanswered questions for my taste, and too many essential puzzle pieces of the background story were taken out and sold separately as DLCs. I don't like it when games do that. However when it comes to influencing the story by your decisions, I think that Inquisition equals Origins.
