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 :(
It love the story too, it was really sweet in a way. I’m kind of surprised they never adapted it to film, but maybe Bobbin wasn’t the most charismatic main character for it considering you never see his face!
Plus it had nice music, lore and even voice over on few versions. I wonder what happened that it never took out until the scummvm player became a reality…
