I can't edit my first post, so I'm posting a new one.
I've been playing Paper Mario the Thousand Year Door lately and I found some parts that were sad without having anything much to contradict it.
One was Admiral Bobbery story to why he never went back to sea. Also when he read the letter that Scarlette wrote him on her deathbed. Then when Bobbery is attacked by the Blue Lava Bubbles, or whatever they're called, and asks that his last request is to have his Chuckola Cola. What makes that even sadder is that Flavio won't even give it to you even after you tell him that Bobbery is dying.
The other is a bit awkward, but still sad. And that's with TEC. Even though it was awkward that a computer was in love with Princess Peach, its still sad to see the X-Nauts shut him down when Sir Grodus finds out TEC has been helping Peach. Then when Mario and co find him, and everything goes red.
