Romantic Friendships
This is tangentially related to this topic but I wonder how much the "romantic friendship" element will be played up. Basically, those people who AREN'T strictly love interests but who have deep and abiding relationships with the PCs. I always worry that's going to get lost with the focus on romances in these games. Alistair's relationship with the Male Warden was one of the deepest ones in Origin and I also loved the close and abiding relationship between Mage PC and Wynne (even if they disagreed on EVERYTHING).
Morrigan and Male PC are arguably better without the romance element (even if they have a child together) because they're such good friends and with no expectations.
Dragon Age 2 had some good bits there but I always felt Anders and Merril lost something if you didn't romance them.
