Skyward Sword HD, and it's my first time playing the game too. It's decent, and it's nice to have a more traditional 3D Zelda title on the Switch (not slagging on Breath of the Wild, but I felt it strayed too far in a few areas) but this game is proof that linear games can be just as padded as some open world games.
Do a bunch of busywork between dungeons, fight the goofy black monster three times (seriously, what the hell kind of monster design is that?), and find three lyrics to a song! Bear in mind that I'm playing the "streamlined" version, everything would be so much slower in the original version.
I'm genuinely impressed that Nintendo found a way to make such a linear game feel so bloated.
