Saga Is the entire plot while this remake Is only the Desire city part route where She become a prostitute. This remake Desire part Is revisited/renewed thought.
I honestly didn't like the First renalith saga style. I think this remake Is a good game but the level of mosaics Is too High so It demotivated me from playing It. This remake Is more similar to kunoichi Karin style of UI, Maps areas, etc...old Renalith looks more barebones or rough, less polished but maybe you should try It because the game Is longer and actually offer the whole plot with 2 routes instead of Just the virginity loss/work in desire as a slut route.
