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 :(
I played the second one ages ago. Nothing more creepy than being a bit of a dick to you people and have a voice whisper your name late at night.
(For those who don’t know: the game would read your username and if it was in the database of soundfiles it would play that whisper at random, but long intervals.)
