Assassin's Creed had a lot of protagonists Who felt love and for me it is an important thing that a protagonist has someone of special in his/her life, because we know very well how much the assassin's life can be bad.
Anyhow in Odyssey and Valhalla the romances aren't default and the we can choose our lover,but this thing a bit ruin the franchise, because like I said the romances can be very important in the story of the game,but if someone can be romanced, we won't get the same effect of the other games.
The only thing Ubisoft can do,but that the probably won't do anymore,is putting a default romance like in Odyssey.
Personally I am one of the few people who liked that romance.
I've always thought that my version of Alexios at a certain point would chossed to have a family,but like I said this thing will change in Valhalla.
We have the possibility to have also a long term relationship,but I had thought it would have worked different.
They said that after a group of missions you could date your lover in the settlement,but this thing doesn't have an impact on the story.
After the East Anglia story,I finished the Petra's missions and began a romance with her.I liked the fact that finally I could have a "real" girlfriend,but with the time my opinion has changed.
During the story a lot of important events happen in the Eivor's life,also in the settlement.
And when these happen,what does Petra do?
She is my girlfriend,but She practally doesn't care me.
This One of the reasons because of I began a relationship with Randvi After the Gunnar's wedding.
She has been more present in the story.
Also if Petra was my girlfriend,it seemed that Randvi was her.
So I hope that in the next DLCs,also the new yule festival,and in the next games we will feel more the impact of the romances in the missions.
