Any JRPG? I can think Persona 5 takes easily 4 hours before you first get to really explore the first palace. It's a genre that needs you to have some degree of enjoyment in just watching the story as part of the game. Persona in fact makes it slightly more bearable, because it's part social sim, part visual novel game, so you actually get to play the social sim part early before you start dungeon crawling
If talking specifically about long tutorials, then Kingdom Hearts 2. Still an awesome tutorial, it's just not for everyone. It would never work with modern audiences, indeed it quite didn't work at the time it was released
