'Super Mario 3: Mario Forever' is a free game released in 2003 by an indie game studio called Buziol Games. According to Bleeping Computer, an IT news site, it has been well received for incorporating new graphics and music while inheriting the elements of the original Super Mario, and has been downloaded millions of times so far.
