No, but I did catch the feels when my kadan gave me a hickey. I think the fact that he'd sacrificed so much in my playthrough - becoming Tal-Vashoth to save Krem and the Chargers - made it pretty meaningful, esp. considering I was also Tal-Vashoth. I swear I will convince him in my headcanon to marry me in the future. The others were nice as well. I like Cassandra's where she becomes Divine. The ambiguity of it all was great in contrast to the others, because you could just tell that some serious changes were gonna happen on a grander scale - esp. with the final reveal.
I really liked and simultaneously despised DA:O's Elf-Alistair romance ending since he dumps you, but I otherwise liked the ending in itself. I like my Morrigan romance ending the best. Especially because of Witch Hunt.
As for DA2, the only thing I didn't like about it was how abrupt it was. There was such a huge emotional investment in Hawke's story - which was like a DA Origin story on steroids - and then we get this abrupt and clearly rushed final act. Left a sour taste in my mouth.
