Well, Super Mario Bros and Super Mario Bros 3 are both great,
nostalgic games that are great for people of all ages. But, Super
Mario Bros is great because of the fact that it is so simple and
basic, that it's fun. Super Mario Bros 3 is more advanced in music,
graphics, and gameplay. So, Fun and Simple is Super Mario Bros, but
Good-Looking and Challenging is Super Mario Bros 3.
