It is usually in ipatches where we see how actualiy game was written; as incest game or not. Some sentences doesn't make sense, like: "ugh dude, that's gross, we are roommates"... " I cannot go out with my roommate"... If she only wasn't my roommate..."
I have no problem if game is or not an incest game, I will play it, but if I I ware against incest games, I would miss probably 75% of all good games here. Or read (without patch) such illogical sentences...
I dont care that much about incest too... there is enough other good reasons why a relationship can be difficult or even taboo... (mother of the girlfriend, teacher-relationship and so on)
I dont even need "taboo" in any way, in fact my most favorite games around here dont have incest or something real taboo going on in the main-lovestory. But if a game has written dialogue like the ones you mentioned, it is clear how the game is really intended, and SG has those dialogues/monologues a lot. But it could be easily fixed too... In the same way you mentioned for example. Growing up "like" brother and sister is adding a taboo thing... i can even relate to that, i grew up with a girl too, she was in foster care by my mom... so not exactly my sister, but "felt" like it for many years... though, we never reached the age together where it would matter for something "lewd" (she wasnt in care by mom anymore when we reached the age of 10).
But yeah... the taboo releationship between Nami and MC doesnt make any sense if they are not related how its written in the game without i-patch...
I didnt play chapter 5 yet, cause iam waiting for the full version, and MAYBE things will change with that full version so the relationship works without i-patch... than iam fine with it, but as of state of v4.5... I-patch makes way more sense.
*Edit* oh yeah... and if Ocean doesnt change those things... whoever makes the i-patch, please keep going... (something tells me that ocean himself has his hand in it though... maybe he is not doing it himself, but he knows who does it and cooperate with him/them)
