I love how I referenced Ultima 1, but you jumped right to Ultima 6. Because you realize I'm right. The main quests in Ultima 1 are so bare bones and linear, you'd consider it a JRPG by your argument.

Also, Final Fantasy VII lets you play a piano with your controller. Various other JRPGs have dungeon puzzles. And a Dragon Quest game has you collect parts to make a balloon. But as usual, somehow it will all be "exceptions."
