>>31172719>is straight considered bad>when the issue is the lack of father characters on screen, not somehow a portrayal of all heterosexual relationships being badDo you not know what straight means?
Initially, in Gen I it was probably supposed to reflect the "typical" Japanese family life: Mom's at home, Dad's always out, kid goes out to play in a park or something to collect bugs. Except instead of a park it's an entire county and instead of normal bugs they're magical monsters.
Everything since then is probably just following formula and muh patterns like a lot of other idiosyncratic things about the series, even as the series got more global in scope. The only one actually probably lacking a father is, oddly enough, our most recent protag. Since they and their mom literally just moved half way across an ocean and there's zero indication of any sort of father even where there should be something. Even with the lack of indications in other games, they're also mostly just leaving from a long term home and certain normalities can be assumed. Or, in Gen III, they also just moved but they're the only ones with an actual on screen father. Who is incidentally the cause of the move.
There's not too many couples because it's a kids game and they don't focus on that. When they do, they come down largely on the straight side. Note the whole Male PC/Shauna thing in XY and what the devs said there. Heterosexuality is the assumed norm, and makes the odd exception, like that Hiker in BW/BW2 and the school girls in ORAS, stand out. We still have a few versions of a couple class, several major characters with families and opposite gender spouses, and so on.
Only the PC is ever really lacking both parents. Siblings too, interestingly enough, though no one every brings that up.
