Trip World for Game Boy. This title was only released officially in Europe and Japan. In Europe, it is arguably the most sought after title! In addition to being rare, the title is cool because it has a whimsical, friendly style and feel to it, and has been compared to Kirby's Dream Land in this regard. The title is also interesting because not all the characters you meet are enemies - some are NPCs that simply walk by you, which isn't often seen in a game.
