Commenting not only on this work, but all of the 'Retelling' stories as a whole ... UD is pretty upfront about his quirks, motivations and author appeals. Nothing being perfect, I find these stories good to read simply because they focus on the characters themselves, they expand and develop each character in a way that is usually believable.
I haven't taken a real interest in Touhou if not for the past few months, but I'll say that reading UD's stories gave me enough of an interest to come here, the Touhou Wiki and other places to find out what this is all about.
At this point I've played a few of the windows games, 1cced IN on easy (nothing special, and I got lucky, I'm still learning) ... all of this stated to make the point that my opinion is valid simply for what it is, and nothing more.
Does the fact that UD has a very strong alternative character interpretation of Yuyuko, a completely different take on the 'cannon' events of PCB, or the fact that he likes to get just about every single character naked for seemingly arbitrary reasons appeal to me? No, none of these things do. I accept them because I still find his stories engaging, and the characters he writes interesting.
I honestly enjoy a depiction of Touhou where character interaction and plot progression involves something more than a series of pointless danmaku battles ... even if that is all that really strictly happens in 'cannon'.
To UD ... I'd thank you for providing me one perspective on this fandom ... I find your stories highly interesting and entertaining to read.
