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 :(
Yep! Loved the gameplay on DS and was excited at the time for the sequel coming. Must have slipped my mind over the years because I never did look into it after it released in Japan.
I googled it and there is an English translation available for it if you ever wanna emulate it!
