Third component of the MEY trilogy, this game featured mostly miscellaneous activities unique from the other two titles.
For a more in-depth review of the series, see Mario's Early Years: Fun With Letters, since the trilogy shares the same graphics, sound, and gameplay. This game mostly features little kid things that didn't fit into the other ones. One mini-game involves sorting. The player has to pick which object out of four is different from the others. Another involves size. The game will show you three of the same objects, such as horses, but of different sizes, and then you must find the smallest, or biggest, or middle-sized one.
Mario's Early Years: Preschool Fun is a nice change from the other titles, since it features a greater variety of games and doesn't focus on a specific area.
