What to say about Katawa Shoujo, a game/visual novel about dating disabled girls? i raised an eyebrown at first, but started playing it because some people said it was awesome. 
So i started playing, got into Rin Tezuka route (an artist girl without arms, how awesome is that?)  and, oh boy, that was an experience. A touching, sad,  yet beautiful tale about restoration and hope and to find oneself and to find peace. (Thats my interpretation at least!)
It was heart wrenching but just the ending (the good ending) made all the tears and sadness worthy.I dont remember being so emotionally attached to a videogame since Xenogears or Metal gear solid 3.
