Can somebody help clarify the difference between nukige and nakige? From context I'm guessing that "nukige" refers to porn games and "nakige" refers to games whose purpose is to make you cry.
Correct! Nukige are porn games, but have a different connotation from H-games, I think. H-game refers to any game with sexual content, but nukige totally revolve around the porn. Katawa Shoujo, for example, is an H-game but not a nukige. And nakige are like utsuge in that their purpose is to make the player cry, like you said, but the VN database says that while utsuge are generally hopelessly depressing, nakige are emotional but might have happy endings. I love learning new words!
From a different viewpoint, p'raps you're pulling and just being upfront on what you're here for if'n yanno what I mean~ /Welcome and heyo, have fun puttering around un ^_____^
The good news is that it only means that in Japanese or when the context has already been established to be sexual and/or S&M. Takeaway: you're fine except in New Zealand.
