All I know about BioWare games is stuff from my sister.
And I am incredibly jealous of my sister, she loves BioWare games and somehow has gotten into the 'in-circle' of them due to connecting and luck. When she goes to cons she often hangs out with friends she's made, and through her friends she keeps on making new ones. There was a cosplayer who she was close friends with who ended up having a major voice role in Inquisition, and the person she voiced impressed Troy Baker, and they bumped into each other during Comicon and apparently he loved her work in Inquisition and it was the 'waifu' in the game, so my sister ended up hanging out with Troy Baker and some other voice actors, who lead to them hanging out with Bioware developers and now they follow each other on their personal twitters, and while I'm happy for her, I admit being a bit jealous.
But she blabs to me a lot about the games, and I know her favorite is the second Dragon Age game, even though it has flaws, elements appeal to her. She originally liked Mass Effect a bunch, but Dragon Age has settled as her personal favorite game series. I haven't played them, but I know a hell of a lot about them because she loves to talk about them with me.
