Hmmm...yeah. I may have to steal @kirie's "Nope!" gif, if he turns out to be a true villain. I probably will end up spoiling myself on his romance arc, before playing. I can do angsty or heightened drama play throughs later, but I just can't do them on the first run. Interestingly, regarding DA, this will be the first game that I read up on a specific romance BEFORE playing the game. LOL!
DAO and DA2, I "lucked" out on the first runs (from a romance perspective), since I didn't spoil myself with those two games. I went into DAO completely blind, and DA2, the only two things I knew was that we were NOT playing as the Warden, and that Anders was a companion again (that was a total accident finding that out; had gone to his wiki page to look something up for my third run through DAA, and they had already put up a picture of him in DA2

That was just a couple weeks before DA2 came out.).
In DAO, I happen to run with a human noble who didn't even KNOW she was in a romance with Alistair (did I mention I had
no clue about the game, before playing it

), and since I had him do the DR (cuz....sure?? why the hell not. Heh!), we lived and married. Though, it sort of felt like an arranged marriage, since I didn't realize I had romanced him.

As for DA2, "noped" out of Anders, pretty much from the get go (since Justice was a big red
UH-UH!, and ran into Fenris. Worked out quite well.

Subsequent run throughs, I varied the role playing with gender, class, origin (for DAO), quest choices, personality and romance. Still, have never desired a "in love with the villain" type romance though. *shrug* But that's just my feelings about it.
