Well, this is very informative. Thank you. I knew of some of these already and I was already familiar with ero famicom games. I spent a lot of time listening to pc-98 music too, so if you tell me about them I might recognize some names. What do you mean by "loli games" meaning something different now? Also, what are Visual Novels called in Japan? They don't have a general term for the medium?
I really don't like the sequelitis many visual novels seem to have. Having so many things be a massive franchise is sort of offputting. Alternative, ultimate, zero, redux, etc. After reading Narcissus, I don't get why it needs anything else to tell its story.
