Oh and something really important, if you have a game where you date characters, add options for gayness please. There's no good reason to block that off most of the time.
This. Some games really block that hard intentionally with often very little reason to.
As you say, more overall representation would help. Sure would get more different perspectives into development.
Then the dev never choose to add diverse leads because they cater to all you dorks who say "I dOnT pLaY gAmEs tHaT fOcUs oN SeXuAliTy"
Yep. Not to mention the publishers that have, for literal decades, pushed against any tiny hint of non-cishet stuff in games regardless how minute. People pretending that the force is about forcing devs to add it are so full of it, lying through their teeth. The pathetically low amount of non-cishet stuff in games was incredibly hard fought, usually by a lone queer dev. Anyone remember the Sim Tower protest easter egg? I sure do.
We know the push is hard the other way and still is. heck, we can't even give female characters boyfriends without goobergobbers freaking out, and there's always a push to make women more ~vulnerable~ and ~available~ for the presumedly male audience. Even the tomb raider reboot was designed around that entire concept, not about emphasizing with Lara or even identifying as her, but wanting to ~protect~ her. Because god forbid a player emphasize with a character that's not a straight dude.
Imagine Sekiro being designed about wanting to protect poor, vulnerable, shy Sekiro-chan while every animation played up his suffering with moans that sound oddly sexualized. Just imagine how weird that would feel. That's Tomb Raider.
Ultimately, the issue goes deeper though. Studios don't give queer devs spots usually, female devs have to work twice as hard to get to the same spot, and a good number of male devs oddly keep working hard to keep things that way. Some, like Jonathan Blow, are nowadays outright stating that women just don't have it.
The games industry is notoriously unsafe for non-straight guy people. Like, even the regular tech industry is better, much better in fact,
and that industry already is considered bad for people that aren't cishet men. The games industry is notoriously bad. It's a vicious circle at this point:
Studios do their best to keep anything out of games that's not solely catering to guys, marketing solely caters to guys, platforms like steam see no issue with rape glorification (only with the backlash against it), devs loudly proclaim that women just aren't as good, and studios love hanging out non-male devs to catch the backlash from a reactionary crowd while the studio twiddles its thumbs.
So people that aren't straight guys have it harder to get anything that inspires us, or make stuff ourselves, so people don't see us, and argue there shouldn't be spots for us/we don't have it while marketing encourages the crowd to take games as guy-only and attack anyone else. No wonder gaming's so toxic. It's grown that way. Gaming didn't end up in this spot naturally.
