I'm not sure if they're really hinting at homosexuality. In the Pokémon universe, everyone seems to love each other.

Yeah, like VGP posted, Erica Anderson from the Catherine videogame. One of the best written LGBT characters out there. Not without certain flaws, of course, but no one is perfect either. 

EDIT: Might as well add an image of her too

I'm not even sure how many LGBT characters I've actually played. Not very many :/

My mind instantly went to Ellie from TLoU though, because not only is the probably the most prominent LGBT character in AAA gaming, lets face it, she's awesome as well!

Other than that I really enjoyed playing Shovel Knight as a lesbian lady knight. :P

Movies are very stereotypical, making a social archetype for LGBT characters. This prevents most gay characters from really speaking with a gay audience, but rather just a hint of social color and amusement to tickle the minds of standard, heterosexual, audiences. It is merely source material. Video Games are even more segmented in their character definitions than film. So there are not many instances of meaningful gay representations in either medium.

Thankfully, Video Games do try to be inclusive with the main character because they try to allow you to make the character as you see them. Not all games, but many. There is nothing from stopping you from seeing Samus as gay or thinking Link might just be a heroic, caring guy who just also happens to be gay, in most games (maybe not Skyward Sword). The moment a game starts forcing a perspective is the moment it begins to alienate certain groups of players. I actually really appreciate games that allow for more flexibility such as SIMS, Rune Factory, or many Nintendo games that have a bit more consideration in their design. Whether you are homosexual or heterosexual, guy or girl, republican or democrat, etc., it is nice to feel like we are a part of a larger world and there are options in freedom. That our purchase hasn't completely closed off a whole subset of personalization and possibilities just for the sake of "who said what why."

There's not many that I know of. Hmm. The only ones I know of were in the dragon age and mass effect games. I liked Samantha Traynor. She was likeable as a character and her being gay wasn't exaggerated or shoved into your face so she came off as natural.

I hated Sera from Dragon Age Inquisition. She's an idiot. In general, I don't like any of the characters from that game.

Who cares? FFS when I play a game I couldnt care less about the sexual orientation of a videogame character...
Get real, I'm all for equality and stuff, but stop this nonsense.
If you want to be equal, act equally!

Where is the thread asking whats your favorite heterosexual character? That's right, it doesnt exist... 

Geez, had to google 'LGBT video characters' because all I could think of was "T....trans....transformer....Optimus Prime?"

Anyway....
L = Asellus (SaGa Frontier) I remember playing this a ton, and teenage AG was particularly interested in the idea of a woman with wive(s).

G = Meiyuan (Shadow Hearts) A creepy stereotype, but I enjoyed the old lech. Every character had to submit to some accupuncture therapy occasionally to get stronger, but all the guys were wary & sore about the process while the girls act like its a breeze.

B = Main protag (Saints Row 4) May be a cheat, but this might be the most fun I've had playing a bi character.

T = ....uh, still stuck on Optimus Prime here. Birdo/Birdette wins by default I guess?

Dude, chill. There are a couple threads already asking what people's favorites men and women from video games are. This is just a simple question about a favorite character with a particular quality. If you're so offended and don't even have an answer to give, don't click it.

But as for the OP, I'd have to say Erica from Catherine, as some previous posts did. I like my sassy McDonald's colored waitress. 

None because a fictional characters sexual persuasion has fuck all to do with anything.

It creates depth in a character. So, if all that matters is gameplay, then yes, it's meaningless, but if you care about characters and the plot, then it is important.
