I think the short length is one of Luigi's Mansion's strengths. It makes it very replayable. I wish that when Nintendo announced the remaster of Luigi's Mansion 2 on Switch, they would've included the first game, too. Made it a collection. Then you could play ALL the Luigi's Mansion games on Switch! Well, except the arcade game. Have you ever played that one? I bet it wouldn't be too hard to put the arcade game on Switch either, since it just uses assets from Dark Moon.
You got some GREAT deals on those GameCube games. I hear that Paper Mario: The Thousand Year Door is insanely expensive. The Mario baseball game was actually made by Namco since they're famous for their Famista games. And Kirby Air Ride is highly underrated. I personally think it's better than Double Dash.
One good thing about Tears of the Kingdom is that it has actual dungeons this time. They were a lot of fun.
