I would love a new Mistery Dungeon with a story of the same level as Explorers of Darkness/Time/Sky. It's the game I replayed most times in my life and one of my favourite ever. It has a very good gameplay and a beautiful story.
Agreed.
Full disclosure, it's the only game that's made me, uh, ugly cry. Several times. Per playthrough.
The story is kinda simple on paper but boy howdy does it get pretty dark for a Pokemon game and the pacing of the gameplay just
masterfully balances out so you have just enough time for each plot twist to fully sink in before the next one comes up. It's kind of weird, I admittedly don't have the biggest library of games but I don't think I've seen anything else exploit the gameplay -> cutscene -> gameplay tempo like that.
Also that has to have been the longest postgame I've ever seen in a game, almost as long as the main plotline itself!
I think the one thing that could have possibly made it better would have been being able to make my -own- guild after a certain point. I think a Mystery Dungeon game on the level of Sky with all Gen 1-8 Pokemon and that option would easily rank as one of my favorite video game titles ever, and Sky already gets pretty close to that territory.
