Happens to me all the time. There’s always curiosities hidden away in the dark corners of a console’s library.
Just recently, I happened across an article on Hardcore Gaming 101 about the DS game Orcs & Elves, which I never heard of. It led me down a rabbit hole which included Mazes of Fate, Fighting Fantasy, and The Dark Spire, which subsequently led me to other DS games unknown to me like Thor and Glory of Heracles. Haven’t played any of them yet, but I really want to get to one of the local retro game stores to see if I can find any of these.
