My go-to example for something like this would be what became Oracle of Ages, and Oracle of Seasons. Originally, they were supposed to be THREE games, with each one themed around a different part of the Triforce, and back in the day, hearing that got me pretty hyped. I was pretty disappointed however, when it was announced that they were reducing the games to just two because it was too difficult to work out a password system for linking 3 games as opposed to 2. The game based on the Triforce of Power would have focused more on combat gameplay. The game focused on the Triforce of Wisdom would have focused more on puzzles in dungeons. And the game focused on the Triforce of Courage would be focused more on interacting with characters to progress, along with having Ocarina of Time's day/night system. Honestly, it all sounds pretty awesome, and maybe it was too ambitious of a task to complete. If only they could have worked out the password system. But it's this reason that I never had an interest in Oracle of Seasons, or Oracle of Ages, because these were watered down compromises that we had to settle for instead of the way cooler idea of 3 games based on the Triforce.
