4 Mario games in one cartridge redone beautifully.
The graphical upgrades are nicely done and give renewed life to the games. The music is also redone beautifully and sounds great coming out of the SNES. Another feature added to game is saving. The original games did not have the option to save and everything had to be done in one sitting. Of course that added to the challenge of the game, but with the save states, you can just pick and play from right where you left off.
Overall this game brings greater appreciation to the classic Mario games and touch ups are a great addition. If you loved Mario on the NES, then you owe yourself to pick up this collection.
