Maybe a little over-crazy about the entire Dragon Age series, long after I've finished playing.

My favorite pairings are:
DA:O: F!Amell/Cullen, Mahariel/Zevran, F!Surana/Alistair(This one breaks my heart for the social stigmas forcing their break-up/down-grade, but still makes for an interesting story), k!meme Morrigan/Sten, Saucy Recruit/Duncan, F!Amell/Cullen/Alistair, PC/Ali/Zev/Leliana/Isabela ;) -- While I understand the potential for "Loghain Lustcapades" and even knowing that he isn't all bad from TST and TC, I was an Alistair Aficionado first sooo...

DA:A: Anyone/Pre-Justice Anders (So funny and charming!)

DAII: F!Hawke/Pre-Chantry "The Rake" Sebastian, F!Hawke/Not-Angsty Anders, Isabela/Fenris, Merrill/Carver, Bethany/Anders, Aveline/Donnic

I probably won't develop any of my own tales regarding these pairings, but I do love reading others' :)
