Chibi-Robo! wasn't exactly a commercial success, but due to its bizarre nature and quirky characters, it reserved a place in many GameCube owners' hearts, even receiving sequels down the line -- it's got a 3DS entry coming out. The tale of the adorable little robot and his interpersonal issues were engaging in ways we hadn't seen before -- even if it's just a little robot vacuuming a room, it's still quite touching.
