4LS still exists??? Wow. I thought that the members moved on to their own projects.
I'm pleased to see Katawa Shoujo is still alive. It was perhaps my first VN, and although it does contain sex scenes, you don't play KS just for the smut, you do it for the characters.
And, even if the name of the novel is literally "crippled girls" (a mix of a red herring and a "tomato on the mirror"), it avoids really well defining the love interests solely by their disability - something that would boring, flat, and stereotypical.
