That’s a good question, since it doesn’t have a trivial answer. Zelda is basically three or four different types of games in a trench coat tunic.
There’s the open world adventure that the original Zelda established, which is probably best represented by BotW.
There’s the 2D tile-based action puzzler, the quintessential of which is probably LttP.
There’s the 3D “interconnected small rooms”, which got its start with OoT and was so successful that to this day players are arguing that the newest two games are not really Zelda even though they stick to the original concept much more closely.
Finally, there’s Adventure of Link.
Can I ask where the material difference is to a game that requires a Day 1 patch download to work? With a Game Key Card, that patch is simply very large. You can still sell the game, just like a standard cartridge. And the Switch cartridges never had infinite shelf life to begin with, so they’re not suitable for archival either.
