@Felthry Depends on the systems you can access.
If you have GameCube, we highly recommend Chibi-Robo. Big part of our childhood. The original Pokemon Mystery Dungeon games (GBA/NDS) are also good, as well as Balloon Fight (NES) and Super Mario World (SNES). We've also heard good things about Donkey Kong Country (SNES) and Spongebob Squarepants: Battle for Bikini Bottom (GC), but we haven't had a chance to try those ones out yet.
Have fun!
