Good Girl Gone Bad is an excellent piece of ero VN, even as it is at the current incomplete version, with more and better characters, and better developed, than similar titles, and I'm sure it will become a masterpiece within its genre in due time. But let's not compare it with Game of Thrones or A Song of Ice and Fire. Yes, the writer, George R. R. Martin has a friend couple who help him with the character database and other details, and they even co-wrote together with him The World of Ice and Fire, but he has 2300+ named characters in his books, we're talking about completely different scales. I understand that Eva Kiss does her work almost completely alone, but I'm sure her difficulty in writing new material, where she has so many characters and path variables compared with the common VN, is in technical difficulties and the ammount of work that may come with those numbers and not because she may confuse them or forget some details. It's like a tree that has one main body and starts to branch up. The more the branches, the more the work required.
