3DS semi-afk/idle games

So my favourite game ever has been Old School RuneScape.

I maxed an Ironman, totaled 6000hrs time play, and really enjoyed being self-sufficient and the variety of ways to play (high-intensity/high-xp methods, chill afk-ish slower methods).

Recent life stuff means I just don’t have time to invest anymore as everything is far too slow e.g. gear upgrades, post-max xp milestones.

I am currently 1.5hrs into Fantasy Life which I’m enjoying for the variety of the Lifes and freedom to explore (similar to OSRS in a way). It’s just missing the tap & wait training methods for when I want to super kick back and chill.

So was wondering if there’s anything else that might scratch this itch on the 3DS?

Perhaps a very niche request, but any recommendations are very welcomed! Thanks in advance :)
