I like* how the houses in Athens look like toy blocks. There's a joke to be made here about the Greek economy.
Not sure how I feel about the inclusion of Moonview Highway, though. The Booster Course Pass already has a great many city tracks thanks to all the ones ported from Tour, and Moonview, as a traffic course at night, feels like it fits into the same kind of aesthetic and functional theming that N64 Toad's Turnpike from the base game does. The music might end up carrying my opinion on the track, though, like how 3DS Alpine Pass' does.

For most of my time with my 3DS, I used a 4GB SD card, which I suspect came with the system itself. I almost never got non-demo games on the 3DS digitally, and most of the games I played weren't too abundant in the updates, so it was enough for my purposes, even if I was skirting at the edge of how much it could store. When I modded my 3DS shortly after hearing about the 11.17.0 firmware update, I figured I'd need an upgrade before modding it, so I went with a 32GB microSD card that was lying around in my house's storage tub, waiting to be used.
Are you checking the "Remember Me" box when signing in? In my experience, if you don't, Kbin forgets that you're signed in very readily.
I suffered from something comparable for a while on desktop... until realising that I never checked the "Remember Me" checkbox when logging in. Maybe check to see if that checkbox exists for you next time you log in.
I played the first two Splatoon games quite a lot, but elected to skip the third, since I felt, and still feel, it'sn't changed enough from 2 to justify itself as a same-system sequel. In spite of that, I was fairly active on the r/splatoon community on Reddit, but'ven't'd any Splatoon interactions on the Fediverse yet. That's probably at least partially down to me not contributing as much here as I did on Reddit, though; much of what I did on Reddit was answering questions about videogames I cared about, and most of the communities for games I care about here either don't exist to my knowledge, or are small and subsequently have relatively little content to interact with at all, much less people posing questions about the game.
