Main line story and optional romance quest are acceptable.
I’m not a romantic dude… AT ALL so for me my knowledge is very limited:
Tidus X Yuna - Final Fantasy X
Shepard x Jack - Mass Effect 2 (I actually adore this one, Jack is deceptively cute)
The… Warden? (Forgot the name) X Morrigan - Dragon Age Origins (She is so much fun to hang out with, I would legitimately fall for her irl)
What do you think about my picks? What are yours?
Might be in vast minority who skips all romance scenes or socialising with characters. dude I am here to save the world not try to impress everyone how cool my character is.
