i suppose its not 'bad' that you don't care, i find most people don't, and the only reason i give a damn is because a monotonous cast is rather boring...
it probably is a gender thing, i like being able to play as a woman (as a woman) but more often then not said females are either unbelievable or poorly written and really only there for tits... its gotten better but meh... yes there is a level of suspended belief, and since most games deal with a kind of 'military blah blah blah' vibe i get there's a general ratio of 30 guys to 1 woman (i was in the military, that's pretty much how it was ._.) so i can 'get' having less women per men in games, this doesn't really bother me as generally the 'type' of woman that would be involved in these storylines actively beyond typical romance fodder would be a bit of a minority of the female populace...
but to be honest, its not about having 'more women in games' to me, its having a freakin' cast that is BLOODY INTERESTING!! and if you look at any JRPG (i know, they're terrible... but addicting) especially the older/90s ones you find the 'cast' to be diverse (most often including some kind of 'animal'-person, woo!!) and while individually said characters might not be all that interesting, in the context of the group it is paramount for this differences as its the interactions that make them all interesting... having them all be generic-white-man of pottentially varrying ages is... not interesting at all ._. there is no dynamic as generally there's probably very little they don't agree on on some level...
in my short foray into helping a buddy of mine and his 'crew' with their 'making a vidja game about werewolves' they brought me in as i'm rather experienced with writing... the first thing i said after reading their scripts/character portrayals/and basic outline was 'so where's the woman?' they looked at me like i was crazy, their thing was generally a racapping of their time in the field as combat veterans with werewolves and they went at length 'there's no women in combat' i just nodded and proceeded to explain 'that's true, but this isn't in a combat zone, its in a modern city, and the only thing remotely not white-male in this story is the MC's dead girlfriend...' i tried explaining to them, as they brought me on just for the task of 'making the story more interesting' and they didn't want to listen to me at all, that this is a 'game' yes it can be based on their views of 'what happens in war' as vetrans but that without some interesting interaction between character, playable or not, and some diversity whatever story they pull out of their asses wouldn't be compelling at all... just because you give everyone different mystic super-powers with some wangsty brooding background does not make them interesting characters, there has to be that ability to interact, to have potential of 'something' and blah blah blah...
they offered to make one of the characters 'gay'... i flatly stared at them and said it was already the gayest thing i've ever read as there was nothing but dicks involved...
i like to imagine this small paradigm of my experience, on a cosmic scale, is how most game development goes... it certainly explains a lot... especially in the games i've played recently... even as a writer, and female, i find i have a larger amount of 'males' in my stories simply because 'male' is default gender for 'i don't care' when making OCs, but my primary cast of characters-i-give-a-fuck-about is generally 50/50 in the gender margin with all manner of races, looks, attitudes, ages, orientations, etc. dynamic makes things interesting and spurns the desire to keep reading/writing...
as someone that just wants to play a game, i doubt most people notice all this that goes into it, as someone that likes to 'create' things myself i can't help BUT notice it... but usually i don't let it be a detriment, i've never seen a female-heavy cast outside a harem game and the only time the hero/villain were female and freakin' AWESOME were in Parasite Eve even if a majority of the supporting cast was male (except maybe one or two chicks that ended up being more useful as either a source of information or shop in the second one making them more memorable then the other npcs) so its not like i go into a game expecting 'women' to do anything important... its nice, it really is, when i get the chance to play a female PC because i can connect to it easier and i don't squick as much when my only romance options are other women...
plus as i said... when i see nothing but 'dudes' in the cast/only playable characters, all i can think is 'gay'... i believe that was the first word i said when my hubby tried to get me to play GTA5 and it did pretty much turn out to be one of the gayest-bromance-male-whinging stories i'd ever played... just saying...
