Because it makes the game world interesting ..... otherwise it would be another game with monotonous world like all 5 star games...were you can skip like 95% of content
again imagin game of thrones without any drama ,intrigues ,competition.....
sex VN games have this problem... they are mostly boring
thats why I am worried for SG that it also turns into monotonous world
WIAB has potential to be the best VN in story way ...if ocean use all this things like intrigues ,rivals ,competition,death (bad endings)....,gangs,jeliousy,drama..
