Is that flashcard deck a commercial/community project or is it something you assembled yourself? Sounds fascinating !
I made it myself. I use Obsidian and the Spaced Repetition plugin, which I highly recommend if you want a super simple markdown format for flashcards and use Obsidian: https://www.stephenmwangi.com/obsidian-spaced-repetition/ There are pre-made Geoguessr decks for Anki. However, I wouldn't recommend using them. In my experience, a fundamental part of spaced repetition's efficacy is in creating the flashcards yourself…
+1 to this, have found the same when going through the Genki Japanese-language textbook.
I'm assuming you're finding your workflow is just a little too annoying with Anki? I haven't yet strayed from it, but may check out your Obsidian setup.
