I've decided that, with my current bandwidth restrictions, rather than try to put together another pack, for the moment, I'm going to try and write some scripts for the many girls contained in the packs thus far. (If I can figure out how to do anything at all with the script editor, that is.) If anyone has some helpful tips about understanding the code in the editor, I'm sure it would expedite things, and I'm also wondering if it's possible to use player actions to trigger events that would alter a girl's background story, traits, skills, or other stats.
For example, I'd like to write a trigger that causes Astaroth to instantly love the player if she's given an item that cures sterility, and another that changes her story if she gets pregnant. I also think it would be a nice touch to be able to change quite a few girls' stories when their love for the player reaches a certain point to reflect their change in attitude (e.g. Amy Rose is no longer fixated on her "boyfriend" or Crimson Viper "seems only to love money, her daughter Lauren and you.") I think that though the changes would be small, they could make a world of difference to the experience and give a much greater feeling of accomplishment. Like I said, though, I have no idea whether much or any of it is even possible or if I'm limited primarily to additional dialogue.
Also, when girls are characters in the same show, game, etc., it would be fantastic if talking to girls (perhaps when you chat about general things) could possibly trigger events that allow you to meet the other girls they would know from their respective universes and possibly convince them to work for you, capture them, steal them from rival slavers, etc. It'd also be nice if the girls giving you information was contingent on whether they liked/feared you enough. I think it'd be a really fun addition if you could use one of the Sailor Stars or the girls from Tenchi Muyo that you pick up to find and capture the rest.
Anyway, I'd love to give something like that a try, so if anyone could let me know what's actually possible (and how to do it), I'd love to hear about it.
