Mine has to be Dragon Quest: Rocket Slime, a DS spin off of the Dragon Quest series that sees you playing as a slime operating a tank and rescuing the people from your town. You run around the overworld, collecting items to use as ammunition and saving money to upgrade your tank. The art and music are just as great as you’d expect from the Dragon Quest series. It made fantastic use of the DS’s dual screens. It’s also written for a younger audience, so a lot of it is just really silly and fun! Try it out for sure, I’m so sad there’s no sequel :(
My mom loved this game back in the day. She tried to get back into it recently but sort of bounced off. If there’s any game that deserves a sequel, it’s Puzzle Pirates.
It fulfills a niche that few other games (none that I know about) fills, an MMO where the primary gameplay isn’t an RPG but a series of puzzle games; where most importantly, you can specialize, only needing to play the puzzles you enjoy (unless you’re captaining your own ship solo, in which case you need to be able to at least adequately perform all of the puzzles necessary for keeping a ship afloat).
I think it’s wonderful for giving an audience used to shitty Facebook match-3 games a more involved and social experience of what games can be.
