Oh I shouldn't respond. But I will. Not sure if it helps or is necessary, but I'm a straight, white male.
1) As a heterosexual player, do you feel comfortable having your PC who is not your sex, romance a NPC who is your sex. Like me as a male playing as a female PC who romances a male NPC. Or a heterosexual female who plays as a male PC, but romances a female NPC.
I guess. I did it with my female characters in DAO and DA2. I'll do it again, just to play it and have fun and get achievements, but it's not really my cup of tea. I'm totally for the idea that if people want to do that in a game, go ahead and do it. I romanced Alistair and Zevran as a chick, and I did Fenris and Anders as a chick. Maybe it's my straightness coming in, but they just didn't feel for me. I guess (certainly with my canon run) that I view the character as me, an extension. Who I would want to be in that world, or more how I would react in that world if it was me placed there, who would I romance, what choices would I make, etc. Am I comfortable about playing a PC who is female or even a male and romance my own sex? Sure, it's just not what I would opt for normally.
That being said, I think there is a difference between playing through with the intent of being somebody different and having things happen to you that you may not like. Like I said, I'm white, straight, and male. Adding into that, I'm from an upper middle class family, I'm a conservative, and I'm a brother in a fraternity. Statistically, I'm going to be that straight, "advantaged" guy, etc. If I go to a frat party, I expect to see lots of straight people grinding and slipping into debauchery, especially with how we rage in my school. The first party I went to that wasn't Greek (and wasn't a theatre convention party), I was somehow shocked at seeing homosexual people making out, but also, I was shocked at seeing heterosexual people making out at that same party, maybe because I didn't know anyone there. Maybe I was grossed out by watching people who were gay go at it way more raunchy than how I and straight people at my parties do (at least in public, the bedroom is another story), and I easily can be a stereotypical fratstar when I want to be at a party, but I've always seen a line at Greek parties in public. This one was completely different. It's like how it seemed that all of the DA2 romances openly hit on you. Yes, it's a Bioware video game, but I don't think people were ready for such an open display of affection from people, especially since gay rights are still sort of emerging and becoming more accepted, especially in such a straight male dominated scene like video games. When I watch tv or HBO or a movie, I'm not surprised or shocked, because I expect Hollywood to do certain things since it is considered left of center in politics--generally.
3) As a male, do you feel comfortable playing as a female character? As a female, do you feel comfortable playing as a male character?
Yes. basically what I said above.
4) If you are white, do you ever create characters that out right do not look "white" but rather black, asian, hispanic, or multi-racial? Or do you just stick with white?
Not really, never felt a reason to or go on a "social justice" campaign. My characters are white, but not too pale, pretty close to who I am. I see DA as a pretty equal universe, aside from race like Human, Dwarf, etc. I don't think there's ever been skintone problems in DA, and for the most part (I'm trying to leave politics from either side out of this as much as possible) in the real world--or at least that I've seen here in America--racism and such are really not an issue. The only ones who bring it up are the extreme fringe racists like the KKK or the Black Panther Party (or is it the New BPP now?) and the occasional SJW who seems to think because you disagree with someone you are a racist, misogynist, misandrist, etc. Are there bad racist people? Yes. Is the problem mostly gone now? Yes.
6) Will you be comfortable romancing Vivenne if you are a white male? Do you even find Vivienne attractive? I do and I like how Bioware decided to create a black female with strong African features instead of the typical European looking female coated in brown skin.
Yeah I will. I have a black aunt, so interracial families aren't a big deal to me. Is Vivienne attractive? To me, not really. I don't know what it is, or maybe I just need to see her more or her character personality more before I decide if I find her attractive. I can definitely see how she is attractive, but she just doesn't do it for me. That's not to say I don't find women with African features attractive. I recently met this gorgeous Jamaican woman and wow. Just wow.
7) Will the majority of your Inquisitors be human? How hard or easy is it to play as an Elf or Dwarf (and now Qunari)?
My canon Inquisitor will have an 85% chance of being human. I'm certainly going to play a Qunari in the second run. I've tried Elf and Dwarf but they just didn't feel fleshed out to me. The Elves felt way to whiny, understandably because of their history and circumstances, but I just can't stand people who complain. They were like the modern day keyboard commandos who complain about something but never do anything. Actually, it's not that I hate complaining; I hate inaction. The dwarfs were more fun than the elves to me, and after having them gone from DA2, I'm definitely playing a dwarf again.
