Because writing around it fucking sucks.
Could you elaborate?
Every single thing I write in TiTS - EVERY single thing - requires a variant for the leadin because it's possible for the PC to be nude. So I can't just write a stripping scene where the PC slowly removes items of clothing. I have to also write a variant where they start off nude and frankly, starting off nude can sometimes be fucking weird, like you really shouldn't be able to be nude in certain places. Eventually you don't bother with fancy leadins because writing them is a pain when you are also guaranteed to have to write an already-nude variant that has to have alternate text to explain what the PC is doing instead of taking off clothes. It makes writing a hassle much in the same way being a naga or a taur does, which aren't available as options to the PC for the same reason.
One thing to note also is that the world doesn't start like the sexy apocalypse Mareth was, so running around the buff is going to get someone going "Oi, whatta fook ya doin' mate dinnae ye mum teach ya about knickers?"
The PC is nominally included in these people.
EDIT: As of right now, you can. I think they're using the TiTS appearance generator (yay code reuse!) to generate the description
It's very cold.
Let me reiterate this, it's cold, really, REALLY FUCKING COLD where you are. At least from my understanding this "World" is a winter type world where most of the time it's cold as fuck.
that the overlay is just a framing device for finding smut.
You say "fetish carnival" like it's a bad thing. It's a porn game, so let there be porn!also the best decision in the design doc is to forgo the whole fuck-all-the-shopkeepers thing. That always gave TiTS this fetish carnival feel that felt less like discovering interesting things and more like walking around to look at all the attractions. The problem with that is that it doesn't really feel much like a game, that the overlay is just a framing device for finding smut.
It sounds like Savin wants to make this more of a real game that has smut as opposed to a smut-dispenser.
