It's a good thing you can't copyright an idea, or the likes of Disneyland Kart Racer would no doubt be hearing from Nintendo about their similarity to Nintendo's mighty Mario Kart.
Racing karts around colourful fantasy tracks, collecting item boxes marked with question marks to get power-ups, then firing these power-ups at opponents in order to score an advantage over them. It's all in Disneyland Kart Racer, and it'll all feel instantly familiar to those who have played Mario Kart.
Of course, this game does have some uniqueness of its own. For starters there's its Disney theme, which means eight Disneyland tracks based around different areas of the famous theme park, such as Space Mountain and Pirates of the Caribbean.
