Super Mario World is a platformer video game released back in 1990 for the Super Nintendo Entertainment System (SNES). However, the game was unofficially ported to the Nintendo Entertainment System back in 1995. Although the game features the same gameplay, levels, graphics, and scenario of the original SNES game, the older engine made it impossible to import many of the levels. As a result, the game features fewer levels, nonsensical physics, a series of game glitches, horrible music, primitive sound effects, slowdowns and drop of game performance, and so much more. Regardless, the game is still very fun to play.
