I'm not as bitter, probably because I wasn't around before ME2's reveal. I found it an enlightening and uncomfortable look into BioWare's past. I was only familiar with DA's style of romance content (aside from Valen, I ignored BG2 LI for the ladies and I didn't know about Genn for several years) and I was pretty taken aback by a lot of ME's style. It showed me how far that BioWare has tried to come as a whole with the DA series at least.
I wonder if, because ME was a more mainstream success than DA:O was, if they were using Dragon Age to test the waters fully when it came to LGBT+ content as well as LGB+ romances. I know it sounds a little Tin Foil Hat, but it's something I've mulled over before.
Personally, I'm kinda bitter, because it's been a similar story with the DAI LI's - Cassandra is a tough-as-nails, take-no-**** female warrior, with short hair, a woman in a traditional masculine role BUT SHE ONLY WANTS THE D! And I have some issues personally about how I still feel that 'lovable rogue' and 'sleeps with anything that moves' are still the default categories that they give for male same-sex options over in Dragon Age. The characters can evolve from those starting points, but that's still the core archtype that it seems they go for.
That bitterness also probably has a lot to do with how they were pretty much dragged kicking and screaming to get not just male same-sex options, but an ADMISSION of Liara as a bisexual romance. I remember a LOT of hemming and hawing about how asari 'didn't really count' since they're monogender, even though they openly admitted that the asari were designed to be attractive as love interests, and, based on that, it's easy to see that as 'heterosexual male love interests.' At one point, someone said that Shepard was 'too predefined' to be homosexual, a statement that was rightly torn apart.
I've been burned before by Mass Effect's attitudes on same-sex romances, basically. So I'm a little gunshy and paranoid about what the option will be, because it was like pulling teeth to get what we got in ME3.
