I do believe that, for a new IP, BioWare should feel free to not include any player romances.
However, for Mass Effect and other established series where romance has been included traditionally, it's probably going to cause a bigger outcry not to include it. I could live without romances in my games.
However, I will say that, as a straight woman, it's kind of nice to have the option for romance there in something that isn't just a dating sim that is solely about romance and nothing else. For straight women and for LGBT people, being able to romance someone of those specific preferences is a rarity in any kind of game outside of dating sims. For guys, well... usually your male protagonist has a love interest, even if it's scripted and you don't have options. It does add to the connection to the characters and the plot. I do enjoy the romances. And I do enjoy gushing about them, and see absolutely nothing wrong with everyone who likes a character and enjoys romancing them gushing in a romance thread. It's fun.
I don't want a dating sim, though, and I think some people do. Romance should be a side bonus, not the be-all and end-all of the game. I get why people are annoyed by the focus on romance--you know resources could be spent on other parts of dialogue, building comeraderie etc. And some people are downright creepy about their preferred video game LIs. (Believe me, I've definitely been creeped out from time to time, too, even within groups where I actually also like the character in question.)
And that's the thing--those of us who do appreciate the romances, well maybe some do like dating sims. But most of us are playing the game for the story and the lore and even the gameplay. But, romance definitely adds something to the experience for a lot of people, and that means it adds value to the game to those people.
For me, my favorite part of both Dragon Age and Mass Effect is probably the lore, although I am pretty sure I spend more time gushing about the romances than I do typing out my myriad wild theories. (Well, at least on the forums I do. I've been known to get into chats with other fans and go on and on about Dragon Age lore theories... Probably annoys said people...)
But yeah. I'd be all for "no romance" in a new IP, but 1) they've pretty much already said we're getting romances, if I'm not mistaken (something about alien romances was said somewhere?) and 2) romance is already an established feature of both Dragon Age and Mass Effect.
So I'm going to respectfully disagree with "no romance for ME:A," but wish you luck in getting no romance in whatever the new upcoming IP is--especially since threads were made at some point by a developer questioning how people would take it if there were a game without romance in it. While many of the responders said they enjoyed romance, most also said that they could certainly live without it. This could have been a question pertaining to the new IP that we still know nothing about--but who knows except for BioWare employees?
