No one is forced to be straight…
Virtually every JRPG has a straight romance subplot, typically staring the main character. Every FF since... six? Every Dragon Quest. Every Persona. Kingdom Hearts. Fucking Mario Brothers has a straight romance in it.
Like you think Doom Guy is straight because he’s clearly a Christian?
I think you can head-cannon that the two dudes in Time Crisis are having hard core steamy Special Agent on Special Agent lovemakings in between chapters. Fine and good.
But when Arno & Elise kiss in Assassin's Creed Unity? I'm sorry, but nobody needs to see that heteronormative degenerate filth. Kids are playing that game. What are they going to grow up thinking?
