There are so many more VN's that are really good to read.
Echo project VN's are great but I'm not much a fan of horror VN's.
I watch others who stream or make videos of them. its entertaining.
If you haven't, I really recommend Tennis Ace!
I've read through most of Tennis Ace just have Jun latest update to read.
