Super Mario, as you're probably aware, is one of the few video games that can claim to reflect shifts in common sense across generations and decades. Most people are familiar with Mario, the Italian plumber who usually appears to be wearing a jumpsuit. Anyone can now play it online for free on a PC.

As Super Mario , you must navigate the Mushroom Kingdom. Defeat the dangerous mushrooms along the way, and finally save the princess from the game's main nemesis, Bowser.
