Borderlands 2 has a player character randomly confirm she's jewish because when she opens a chest she can randomly say "it's like hannukah" which is a reference to the first game when another player character would say "it's like christmas" and it's perhaps the funniest way they could've done that
Axton was supposed to only flirt with female characters but they messed something up so he would flirt with men too and they just decided to leave it and confirm he's bi which is again the funniest thing they could've done
just goes to show its easier to make characters bi than straight in terms of programming since you dont need any extra lines to restrict it. game companies are cowards if they dont make characters bi
