I don't even start a new Inquisitor without planning a romance for her/him.
Same. I always plan my playthroughs around who I plan for that character to romance. However, my first playthrough of Inquisition, I went in with the intention of having my elf romance Cullen, but she wound up with Solas. LOL. So 2nd elf went to Cullen. Next lady elf went back to Solas. First male elf is going for Cassandra. Second one is going to Josephine. My human male is going to romance Dorian (probably), and if I still feel like it after all that, I may make a lady dwarf for Blackwall and qunari ladies for Bull and Sera. I find all the romance options really add to the replayability for me, and all the ones that I've completed I felt gave nice insights into the characters. I also love the character quests and feel the romance subplots add a great deal to that. I don't think I could go through a Bioware game and not do a romance honestly unless I just didn't like any of the characters.
