Yeah, sure, I get you, but most developers are always going to go for what is most profitable. Which is why we have so. Damn. Many. Shooters and nary an RPG or strategy game in comparison. Truth is, DA style RPGs (Call of Duty: Black Ops II grossed over 500 million in the US alone in its first 24 hours, while DAO only sold 3.2 million copies three months after its release) appeal to a fairly niche market, so there is going to be less of them. Similarly, LGBTQ content only appeals to a minority of players (even if non LGBTQ players can enjoy it) so there's going to be less of it.
There are two things I'd like you to take from this
1) in an ideal world money shouldn't even come into a decision to make LGBTQ people feel like the important parts of the global community that they are. Why should profit be more important than inclusivity? The mind boggles. The world might run on money, but it's driven by people.
2) this is why it's vital that LGBTQ people make their needs known. They are a market of gamers, potential gamers, friends of gamers and if profit really is the answer then people who support equality need to mobilise support for developers who recognise this. It's a long struggle- many companies still don't see women as a viable market for their products, but that doesnt mean it isnt worth fighting for
