Sounds like I'll definitely be looking at Katawa Shoujo after all. It might still have to wait though since I've still got a lot of other stuff to check out. I will probably also be giving other Key VNs a try. Do you know Tomoyo After?

Oh and speaking of Bernkastel, I might check out Higurashi as well. I've seen the anime adaptation and loved it, so I imagine I'll like it :P
