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 :(
Tomba! It was a really bizarre PS1 game that I was hooked on when I was 9 or 10. You play as pink-haired boy fighting some evil pigs by throwing them into their respective evil pig bags. Trippy as hell.
The only reason I know about that game: https://www.youtube.com/watch?v=H50nqenYMDM
Loved that game back then. Much preferred the first over the 2nd
