Steam is completely irrelevant. Even when Steam was around, Zun was actively against publishing his works on it until very recently. It's not really a primary vehicle for Japanese self-started games either from what I know and Touhou 16 being published on Steam was for the benefit of Western audiences and completely unnecessary in terms of spreading the word.
Just to comment cause I don't think it becoming a success "before Steam was a thing" is the most impressive thing related to that, but rather that Touhou never needed to depend on formalized distribution platforms.
Also those dumb bows are the defining characteristics of all Touhou characters. Can't have a Touhou character without a hat or bow.
