Counterpoint: All the origin characters have bespoke side stories and dialogue, and one of them is a chaotic neutral rogue who is also a bisexual vampire twink.
(Given Sven’s advice here I’m probably just going to go with a drow or tiefling warlock, but Astarion is absolutely on the table for the second playthrough.)
Warning: all of those games contain stuff that can fuck you up if you’re not expecting them, so check trigger warnings as required. That said, I’d also add OMORI and Jimmy and the Pulsating Mass to the list - IMO they are much better than OFF as both games and stories while playing with similar themes.
