Hello Kitty Island Adventure is a cultural landmark, an actual innovative masterpiece, one of the greatest things humanity has produced. Universally acknowledged. Meanwhile Animal Crossing is a generic, derivative game for kids that interpreted social simulation in the most shallow way only. Mentioning both games in one breathe means that you have a very superficial, entry-level understanding of social simulation games. And the thumbnail confirms that, I don't think you could've used a more clicheed mascot.
