@owashii the ones that come to mind for me are:
- Oracle of Ages/Seasons, and to a lesser extent, Link's Awakening was kinda an early draft of the GB/GBC/GBA game engine
- Ocarina of Time / Majora's Mask
I don't really know about Four Swords, does it share with another game?
@frummidge @owashii@plush.city oh yes also tri force heroes shares an engine with a link between worlds
also, the japan-only BS Zelda no Densetsu: Inishie no Sekiban shares an engine with A Link to the Past
