What do you think explains the recent surge in popularity of this genre?

Why this genre, why now? I know there’s been fans since the 90s, but why does the field-like seem to be surging in popularity over the last few years? Was it ahead of its time? I’d argue it’s very much of its time. Is it nostalgia? It doesn’t exactly feel like nostalgia, since these games weren’t that popular back in the day (from my recollection).

We have Lunacid, Labryinth of the Demon King, now Queen’s Domain, and I’m sure others I’m unfamiliar with.

What do you think it is?
