Also what i meant by complication, i think for a linear plotline where each girls are inter-connected and interacted with one another on a frequent basis, the extra back-end processing and checking that is needed to determine for example: render scene X, render 3 models, is model 1 preg or not? no? render model 1a, is model 2 preg or not? yes, render model 2b...so on ; suddenly a scene that is usually a 1 image render now contains variables that made it 9-12 image renders (please cmiiw since i also know nothing about how renpy image coding works)
I think this is also why corrupted kingdoms haven't implement it yet in-game (well there's the daydreaming teaser)
*ahem* but with these understanding aside, i'd still love if it's optionally available in the game, maybe as "happy ending" option or something ;p
