I will always advocate for more media centered around living with a disability. What separates Katawa Shoujo is the emphasis on the emotional impact of disabilities rather than the physical. Emi's story is about her grief of someone else from her accident, Shizune's is about her want for control since she can't be independent, Hanako's is about her anxiety from having a visible disability, Rin's is about how other people think she could never be successful due to her disability, and Lilly's is her unwillingness to rely on others in any way and pushing away relationships because of this. I know it's overall not the most well written fiction in existence, but until there's a plethora of stories focusing on similar themes I'll gladly give this a high rating.
