I'm the opposite, I prefer playersexual for some of the reasons you listed (2020 never represented in games crowd, unite), but I also think that when it comes to most characters in RPGs, they're nothing that actually distinguishes them as just straight. I think that by the very nature of adventuring that companionship would matter significantly than to someone you're attracted to that you may see for a few weeks before you put your upmost faith into another person and hope they'll see you through your travels. That, however, is likely become I'm demisexual and perceive things through that view.
Well, I'm gonna have to disagree with you on the "nothing that actually distinguishes them as just straight" point. Even when a developer/writer hasn't explicitly named a characters sexuality, we live in a heteronormative society. It's pretty much unspoken that Straight is the "default", unless you've made it very clear in your setting that that is not the case.
Also, I'm not sure I understand what you mean in the second part regarding companionship, but that could just be my tired brain lacking reading comprehension, lol.
A counter I would say to your dragon age comparison is that people were HEATED that they couldn't be with Alistar. Overall, I don't think gaming has "good writing" these days (due to market surveys, analysis, profit projections) and I'd rather have a character that is open to being romantic with the person they are risking their lives for as a personal decision than to read some writer's perception of LGBTQ issues because, honestly, that's 90% of the time garbage filler that gets forced through the tubes. Most writers can't even write women (or non bog standard sarcastic anti-heros with a heart of gold) well, and those that can get struck with -- "I like her but can she be nicer?"
This is fair, I'd completely forgotten the whole Alistair thing. Probably because I was too busy being sad about Morrigan not being romanceable (God bless modders for making that dream come true). Also I'm still mad that Sera was such a badly written character. The Dragon Age franchise is so bad at writing lesbians that aren't either evil, annoying or just bad. Sigh.
I guess I was just looking back at Dragon Age with rose tinted glasses, thinking about Leliana and Josephine, whose romances I absolutely adored.
You're absolutely right in that we've got a long way to go with LGBT characters, and writing in general, before we'll ever see more than like one or two well written LGBT characters in all of video games. The best solution would be more LGBT writers and game prodcuers.
