Strange that Type Moon VN's don't get a Steam release, you'd think they know there is an audience there.
weirdly it just seems like a Tsukihime thing specifically
Witch On The Holy Night is on Steam already and the upcoming Fate/stay night remastered has been announced for it as well
although the former did take a while to get there so perhaps that's the idea here as well
