it could be a branching dialogue option. If you want to add more than one scene per girl, you could also make them challenge the player again, but have a modifier (I.E you can't use a certain move or the girl's stats are buffed from their original fight) to get additional scenes with that girl.
I have a lot of characters in the roster, but only a handful of stats so I might have to get creative.
I like the idea of branching dialogue based on your performance or stats.
NPCs may even be annoyed or impressed if you have beaten another NPC more than once. That kind of thing.
Thanks for the brainwave. I'll let it marinate for a bit and then add it to the game design doc.
Kind regards,
