I remember playing Zelda I on an emulator. The progression was absolutely brutal since the game doesn’t give any hints on where to go. I don’t know how people back in the day did it without guides and walkthrough vids. Still an amazing game that was really ahead of its time (and I believe the first console game to save!)

CrossCode is awesome. Remember picking it up from one of the itch.io bundles a while back and put 30+ hours into it. Never finished the game but it was well worth it.
