This game has become huge with 9600+ images, however it also has become quite difficult to play through all events due to the high number of parameters, e.g. Kane good/evil + dom/sub, Sis good/evil + dom/sub, rank k3-k9 (?), dom/sub skaling for individual characters, submission to selected mistresses, support/sponsorship by selected board members etc.
It would be helpful to have an integrated gallery which shows the player how many (lewd) events were found so far and how many are still too explore on different paths.
The gallery would probably be sorted by chapter, however it would be also good to have filters for additional path attributes like Kane good/evil + dom/sub, Sis good/evil + dom/sub, rank k3-k9, etc, so that the player could easily see if all events on a certain path (e.g. Kane dom good) have been found.
Since the game also contains some fetish content which probably does not fit everybody's taste (e.g. pissing, netori, etc), it would be good to be able to (optionally) hide events with such fetishes in the gallery via a filter.
I know that Sancho Mod provides some kind of gallery, however I think such a huge game needs a built-in gallery since otherwise all the players who don't use the mod will have no idea how much content they have missed. I guess that one playthrough just reveals maybe 20-30% of content, so many players probably miss 70+%.
